solve races in replication lpop tests (#13445) 

* some tests didn't wait for replication offset sync
* tests that used deferring client, didn't wait for it to get blocked.
an in some cases, the replication offset sync ended before the deferring
client finished, so the digest match failed.
* some tests used deferring clients excessively
* the tests didn't read the client response
* the tests didn't close the client (fd leak)
