ACCUMULO-2575 More testing to try to get status records created

Test isn't 100% as it outlined some more deficiencies with potential
deadlock. Will address with specific test cases rather than what
ReplicationWithGCIT is trying to test.
ACCUMULO-2575 A test that should catch deadlock from not writing up into metadata
ACCUMULO-2579 Write into the metadata table instead of into replication directly.

This should prevent deadlock -- can still reuse all of the rest of the code to go from status->work.
