unwanted queued replications

[ccomb]

After having a slave node disconnected during one day, the following snapshots appear when the slave is reconnected. All these snapshots are not necessary. Even if the purge process will erase most, we have to check how they appear.
Maybe avoid to reschedule a replication if another one for the same volume is not finished?
