[tarantool-patches] [PATCH] test: wait for log entry

[Sergei Voronezhskii <sergw@tarantool.org>]

replication/sync.result fails on `test_run:grep_log('replica', 'ER_CFG`
which returns null, which means this entry is not found, instead
wait_log 10s to be sure that the entry appeared in the log

Fixes: #3835
