FIX: Change UserCommScreener to use user_ids (#17489)

Browse Source 
It makes more sense to use user_ids for the UserCommScreener
introduced in fa5f3e228c since
in most cases the ID will be available, not the username. This
was discovered while starting work on a plugin that will
use this. In the cases where only usernames are available
the extra query is negligble.
