ReplicationIT: Change test method name to reflect actual operation

The test shouldReplicateNewBranch creates a new change and then
verifies that the corresponding refs/changes/xx/yy/zzzzzz ref is
replicated to the destination.

Rename it to shouldReplicateNewChangeRef to match what it's actually
doing.
