Only log about satisfied binds if they were previously unsatisfied
Only log about satisfied binds if they were previously unsatisfied

Since we validate binds each time the census changes, and since the
expected normal state of a service is to have its binds satisfied,
saying that a bind is satisfied each time is pointless spamming of the
logs.

Instead, we'll only log about bind satisfaction whenever they were
previously unsatisfied, which is more interesting anyway.
