mon/Paxos: only learn uncommitted value if it is in the future

If an older peer sends an uncommitted value, make sure we only take it
if it is in the future, and at least as new as any current uncommitted
value.

(Prior to the previous patch, peers could send values from long-past
rounds.  The pn values are also bogus.)
