FS-6910 #resolve Multiple entry with the same first, last name or extension in the directory would only return 1 entry.  Fix issue where group by would produce multiple row of count(*) result.  Using distinct instead wouldn't solve the issue in SQLITE because of a bug, so solution is to use a subselect.
