extend add_or_remove_flag() to handle str for old flags

Browse source 
If the old flags are given as str (or None), call split_flags() to
convert them to a list.

This allows to simplify change_profile_flags() which now doesn't need to
call split_flags() on its own.

Also add some tests with a str for the old flags

(cherry picked from commit e80caa130a +
 conflict resolution)
