Since I cannot generate the sync error in the test, the commit does not have have the tests. I had to use the temporary code in the source to fabricate errors. The patch,
contains the temporary code and the tests.

During investigating , we found that the replicator would get stuck if there were error of "Invalid delta." This applies to following situations:
CBL works as a pusher, and has computed delta that is rejected by the remote (SG)
CBL works as puller, and has received delta it finds corrupted, unable to apply it on the base revision.
CBL works as a party of P2P, or as a LocalReplicator. In this case, CBL plays both pusher and puller.
The problem described in the CBSE falls in situation (2) above.
