Removes white line when hiding diff comments in MR

Fixes #6071 

See merge request !2407

Fixes issue where firefox does not delete message after comment submit

Issue was **not** in the way comment was being submitted.
`app/assets/javascripts/awards_handler.coffee` was throwing an error.
This error was preventing any js from running after it.
Fixes #1473

See merge request !2452

Use a more sensible message for the AbuseReport uniqueness validation

Previously it was "user has already been taken", when really we were
saying the user has already been reported.

See merge request !2461

Issue page keeps jumping up

This happens when the discussion side is smaller than the sidebar and the sidebar will need to scroll. When this happens I calculate the height of the two and see if the discussion panel is smaller and make them the same height and add a class `no-affix` which makes the sidebar relative positioning so it won't stick to the top.
