Hides tooltip on discussion toggle button when clicking

## What does this MR do?

Hides the tooltip when clicking the discussion toggle button.

Rather than triggering the tooltip to hide we trigger blur. This is because of how _amazing_ Bootstraps tooltips are. They are shown also on focus so if we trigger the tooltip to hide & then mouseover the button again the tooltip still shows.

Fixed issue boards loading issues on large screens

## What does this MR do?

On larger screens it is possible for 20 issues to load (this is the amount per page) & there still to be room underneath the last issue which means the list can't scroll stopping the infinite scrolling working.

This MR checks if there are more issues to load, if there are & the height of the scroll area is less than or the same as scroll height then more issues are loaded. This will keep happening until it is possible to scroll, once it is possible to scroll it goes back to the default behaviour of the infinite scrolling.

Update snippets UI

## What does this MR do?

Updates snippets UI _(mainly mobile view)_ to new UI proposed in #18849.

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

Does anyone know the implementation difference between `app/views/snippets/show.html.haml` and `app/views/projects/snippets/show.html.haml`? I have only been updating the latter as it's the only one I can find implemented. I assume the former is rendered somewhere seeing as there is controllers for it too. But this doesn't seem very DRY from my current perspective.

Improve validity of spec/features/todos/todos_filtering_spec.rb

Previously, we were checking that a CSS selector string didn't have some
page-related content, which, of course it didn't.

Now we check against the actual content of the selector, we use a more
semantic selector, and we add an additional expectation for the text
that _should_ be there, as an additional sanity check.

Trigger autosize update after template selection

## What does this MR do?

Triggers an autosize update after selecting an issue template.

The autosize plugin doesn't react to value changes and therefore doesn't automatically update when the user selects the template. This merge request adds it so that it detects if the editor the template selector is a jQuery object (not Ace editor) & then triggers the autosize event to allow the user to scroll the textarea.
