Public bug reported:

The SQL for finding a user by email address fails to execute in a timely
manner in mysql.

This is due to grouping on subquery when trying to return ID's for IN()
clause.

We need to nest another query between so the IN() clause gets a known
list if IDs with out any group by clause
