QueryProvider: use left joins and fix the use of the "disabled" column.

Browse Source 
The code used union selects; left joins at least are easier to read. In
some places it was also not so clear that the WHERE part for the
disabled column really worked.

The query FIND_GROUP_USERS also needs to take the disabled column in to
account.
