Bug#27757262 MTR TEST RPL_GTID.RPL_MULTI_SOURCE_BLOCK_RECEIVER FAILING TESTCASE

CHECK

Ensure that all the servers are synchronized with each other at the end of the
test cleanup.

Problem: Test RPL_GTID.RPL_MULTI_SOURCE_BLOCK_RECEIVER  fails sporadically
during test clean-up. Table t2 is found on the second server.

Analysis: The test option "rpl_skip_sync" is enabled during cleanup, therefore
all the servers must be manually synchronized. This is done for the replication
channel 'channel_1' but not for the channel 'channel_2'. The command which drops
table t2 from the database is executed on the master before the slave server is
started. It can happen that the change is not yet replicated to the slave when
the cleanup ends.

Solution: Synchronize the slave server of 'channel_2' with the master at the end
of the test cleanup.
