wallet: stop handling chain notifications once wallet has stopped

Browse source 
In this commit, we alter the behavior for handling chain notifications
within the wallet. The previous code would assume that the channel would
close, but due to now using a ConcurrentQueue to handle notifications,
this assumption no longer stands. Now, we'll stop handling notifications
either once the wallet has or stopped or once the notifications channel
has been closed.
