Replace Vue key=index in licenses list table

See merge request gitlab-org/gitlab!21566

**Why?**

In Vue, lists are not re-rendered, but patched when new props come. This
can cause issues when items which are actually different share the same key.

Remove after_initialize, before_validation for discussion_id on Note

See merge request gitlab-org/gitlab!22128

- We're already overridding the `discussion_id` method in Note.  The
  after_initialize callback is meant to ensure there's a discussion_id
  for all notes if there wasn't one created (or it got deleted?)

- after_initialize runs Ruby code for _every_ instantiation whether it
  needs to or not.  I've found this to cause performance problems.

When service desk is enabled suport bot receives
reporter permissions.
This allows quick actions present on service desk issue
templates to be applied.
