Fix assignment of master status on failed servers

Browse Source 
When the real root master server went down, it still received the master
status bit due to how the replication tree was built. The bit should only
be set for servers that are running.

Also fixed a false state change event when the master status bit was
manually cleared from the downed root master server.
