Do not honor gerrit.replicateOnStartup on primary side

Before this change the pull-replication plugin on the primary side would
perform FetchAll on startup if gerrit.replicateOnStartup was true.
Relying on gerrit.replicateOnStartup = false setting on the primary side
was a weak protection against that.
