The tab was being activated before we set the `[commits|diffs]Loaded`
variable, so even when the `/diffs` route is accessed directly, like
from the "Side-by-side" link, the tab was being loaded from its default
source.

Fixes #1887

Have sidebar labels disappear behind content instead of hide immediately when collapsing.

I'm not sure how to make a gif out of it, but I promise it looks pretty :)

Only with this theme it's not an improvement (this is an honest merge request (trademark pending)) :

Updated merge request merged web hook to correctly fire action=merged.

I believe this merge request will fix both issues #879 and #498.

If a merge request was merged via the command line, the correct web hook was fired with the field `object_attributes.action = "merge"`. However, if the merge request was merged via the web UI, the webhook would be fired with `object_attributes.action = "open"`.

See merge request !780

Fixes #879
Fixes #498
