* Fix the team and channel filtering UT to include empty team or channel
* Fix tests that were failing before this change
Once we've activated the team/channels filter tests for PostgreSQL
and MySQL there are some tests failing so this changes fixes them
* Disable team filtering tests for DBs by now

teams when you have users in both teams:
- DB when filtering by one team and searching by another returns users that are in both teams
- Bleve and ES returns empty
