netann/chan_status_manager: remove unknown edges from passive disable

Browse Source 
Modifies the netann.ChanStatusManager to remove outpoints
from the set of tracked channels when it encounters a
channeldb.ErrEdgeNotFound when passively disabling. It is
possible for this to occur if a channel is closed w/o first
being disabled, which may happen if the remote party force
closes.
