Fixed Presence Resource Filter crash

Fixed Presence Resource Filter crash

The AddClientCB method would delete the resourceTypeName
before it got a chance to insert it due to the logic designed
to make the free'ing consistent.  This fix moves the free until
afterwards.  Note that the insert method does NOT makes a copy,
so it is the responsibility of this method to free in the event
that the pointer is not captured.
