FIX: call to mprRemoveEvent in mprNotifyOn.

This caused problems because mprRemoveEvent caused an event to actually run on the current dispatcher if the current thread did not own it.
Threads should own their dispatchers, but removing this event solves a thread deadlock because mprRemoveEvent locks the EventService whereas
mprNotifyOn locks the WaitService.
FIX: mprGetGlobPathFiles for embedded double wild.

Double wild should not be greedy.
