replication: recover missing local data from replica 

In case of sudden power-loss, if data was not written to WAL but
already sent to remote replica, local can't recover properly and
we have different datasets. Fix it by using remote replica's data
and LSN comparison.

Based on @GeorgyKirichenko proposal and @locker race free check.
