ACCUMULO-2255 fix NPE during commit
ACCUMULO-378 When we fail to get the ReplicaSystem, wait a bit before returning

It's the sign of a bad configuration (or bad implementation). If we return
immediately, it will get near immediately re-queued and spam the system.
ACCUMULO-378 Remove API method which accepts an instance of ReplicaSystem.

There's no reason that a client would commonly have this object instantiated,
so it's a bit silly to provide a method that would cater to that case.
