webhooks: include old revision in MR update events

## What does this MR do?

Includes the old revision for an MR in webhooks.

## Are there points in the code the reviewer needs to double check?

The docs do not give an example `update` hook; should I add one?

## Why was this MR needed?

In order to keep web hook listeners stateless, it helps to include the previous revision of the MR in the hook so that it does not need to remember the last revision (which may also be wrong in case of missed or out-of-order events due to previous errors).

## What are the relevant issue numbers?

Use fewer queries for CI charts

## What does this MR do?
It reduces number of queries sent for aggregating counts for CI graphs.

## Are there points in the code the reviewer needs to double check?
N/A

## Why was this MR needed?
For this project (gitlab-ce), loading `/graphs/master/ci` is so slow it times out eventually. I did a quick benchmarking on production and found that it can take 72.5 seconds to only load the controller action variables (there are queries done from the view, didn't look into those). This MR reduces the time to about 2.5 seconds.

Extra improvement could be done by introducing an index on `gl_project_id` and `created_at` for `ci_builds` table, but I can't confirm that right  now.

Fix timing problems running imports on production

Fixes https://gitlab.com/gitlab-com/infrastructure/issues/151

I've found out that in staging, the imported file is not copied fully by the time sidekiq runs the job, this should hopefully fix it. (Tested against staging).

Fix attr reader to force the intended values for source and target shas

## What does this MR do?

When importing a pull request from GitHub, the old and new branches may no longer actually exist by those names, but we need to recreate the merge
request diff with the right source and target shas.  We use these `target_branch_sha` and `source_branch_sha` attributes to force  these to the intended values. But the reader methods were always looking up to the target/source branch head instead of check if these values was  previously set, this MR applies a memoization pattern to both of them.

## Are there points in the code the reviewer needs to double check?

This [commit](https://gitlab.com/gitlab-org/gitlab-ce/commit/6ce25e7b4caa9e94de74378729178c7060d640b2) introduced this bug in the importer.

Sensible state specific default sort order for issues and merge requests

## What does this MR do?

It provides more sensible default sort order for issues and merge requests based on the following table:

    | type           | state  | default sort order |
    |----------------|--------|--------------------|
    | issues         | open   | last created       |
    | issues         | closed | last updated       |
    | issues         | all    | last created       |
    | merge requests | open   | last created       |
    | merge requests | merged | last updated       |
    | merge requests | closed | last updated       |
    | merge requests | all    | last created       |

## Are there points in the code the reviewer needs to double check?

All the bits where `id_desc` was changed to `created_desc`.
 
I hope it's okay, It makes more sense in my opinion.

## Why was this MR needed?

Prior to this MR the issues and merge request were sorted based on `id_desc` by default. 

This MR aims to make the interface more user-friendly by providing state specific sorting defaults most users would expect. 

## What are the relevant issue numbers?

See #15064
