    Fix timeout handling in logical replication worker
    
    The timestamp tracking the last moment a message is received in a
    logical replication worker was initialized in each loop checking if a
    message was received or not, causing wal_receiver_timeout to be ignored
    in basically any logical replication deployments.  This also broke the
    ping sent to the server when reaching half of wal_receiver_timeout.
    
    This simply moves the initialization of the timestamp out of the apply
    loop to the beginning of LogicalRepApplyLoop().
