Fix bug with title hold in NCIP::ILS::Evergreen->place_hold.
Add the selection_ou and selection depth to the parameters when
checking if the title hold is possible. This will prevent the
placement of holds that are basically unfillable.
TODO: There is quite a bit of code here that could be simplified
by using test and create instead of separate is possible and
create calls.
