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().
