Ticket #47581 - Winsync plugin segfault during incremental backoff (phase 2)
Fix description: Apply the previous patch Ticket #47581 against the
replication plug-in (repl5_inc_protocol.c):
Make sure to delete the backoff timer when
1) a replication agreement is removed and the protocol is deleted, and
2) a new backoff timer set and there is already a backoff timer set up.
