MDEV-11504 binlog_encryption.encrypted_master_switch_to_unencrypted fails sporadically in buildbot

Browse Source 
The reason is a simple race condition. Initially the test was meant to synchronize with master
before showing tables, but it turned out that the slave IO thread should fail by this point,
and synchronization was removed along with a server bugfix. Now added an intermediate sync
instead, to make sure that slave has replicated events before the point of failure
