Extend m_avatars lock in NpcModule.CreateNPC over both creation of NPC scene presence and population of m_avatars.

This is required to stop a race where the SensorRepeat module can detect an NPC avatar before m_avatars is populated.
Extending the lock is the easiest to understand solution rather than getting complicated with null checks.
Hopefully resolves http://opensimulator.org/mantis/view.php?id=5872
