It's Sublime Text's fault. Its word wrapping is not code friendly

If `source_branch` option is passed, and target branch cannot be found,
`Repository#update_branch_with_hooks` would try to create a new branch
from `source_branch`.

This way, we could make changes in the new branch while only firing
the hooks once for the changes. Previously, we can only create a new
branch first then make changes to the new branch, firing hooks twice.
This behaviour is bad for CI.

Fixes #7237

Fixed issue boards when not logged in

## What does this MR do?

This managed to get through because their wasn't actually any tests for loading the lists when a user is not logged in. This fixes that by adding a test & also fixing the template not correctly compiling under VueJS v2.

See merge request !7452

Project download buttons always show

## What does this MR do?
Removes `hidden-xs hidden-sm` classes from `download-button` so it doesn’t hide itself individually from the rest of the `project-repo-buttons` block

## Why was this MR needed?
Fixes #23960. Not sure why this element had these classes in the first place, but at the very least we shouldn’t be hiding the Download button at the `hidden-sm` threshold since that’s still fairly large viewport and users with viewports of that size likely still want to download source code.

Fix error links in help index page when access it with url `http://gitlab.example.com/help/` which have an extra slash 

Fixes #24349

Only turn on Sidekiq throttling if column exists

If the database has not been migrated properly, the initializer for Sidekiq will fail to start and cause the whole Rails server to crash. This change checks the existence for the column and allows Rails to start even if the setting has not been added as a database column.

Closes #24452

[ci skip]

Centralized all LDAP config logic in to `Gitlab::LDAP::Config`. We had varying configuration for devise/omniauth and other things. For example, `user_filter` was never taken in to account for devise/omniauth so a user object would always be created, even if the user did not match the user_filter. 

Fixes gitlab-org/gitlab-ce#21195, https://gitlab.com/gitlab-org/gitlab-ce/issues/15396 and gitlab-org/gitlab-ce#13296
