Cannot filter based on the displayed name in /revisions page

Preconditions Sign in to SUMO with a contributor account.

Steps to reproduce Steps to reproduce the behavior:

1. Go to https://support.allizom.org/en-US/kb/revisions
2. Type "Smith" inside the "Users" filter.

Expected behavior The revisions can be filtered for both username and display names

Actual behavior The revisions are not filtered based on "Smith" which is the display name of the sellis1 username. The problem here is that contributors might try filtering via the value which is displayed inside the "Editor" column.

If the username has a set display name, the display name will take priority and it will be displayed inside the "Editor" column instead of the username which makes it hard for users to figure out which is the actual username and based on what should they perform the search.
