Bug#36099 replicate-do-db affects replaying RBR events with mysqlbinlog

      
The replication filtering rules were inappropiately applied when
executing BINLOG pseudo-query.  The rules are supposed to be active
only at times when the slave's sql thread executes an event.
            
Fixed with correcting a condition to call replication rules only if
the slave sql thread executes the event.
