LP14973322: Search for Users by Profile

Stop treating profile like a text value, instead
include users in the selected profiles and descendants.

To test
-------
[0] Search for users by last name (and / or first) and do not
    select a profile, take note of results
[1] Select the top of your permission group tree (Users, likely) and
    search again, results should be the same.
[2] Select a group further down the tree (Circulators, Administrators,
    Patrons, etc.) and repeat the search, there should only be results
    from that group and its descendants.
[3] Finally, select a group with no child groups. Results will only be
    that specific group.
