Post push fix to address test failure.

Problem:
=======
rpl.rpl_drop_temp_table_invaid_lex added as part bug fix has occasional
failures in build bot.

MTR's internal check of the test case
'rpl.rpl_drop_temp_table_invaid_lex' failed.

 Variable_name    Value
-Slave_open_temp_tables    0
+Slave_open_temp_tables    1

Analysis:
=========
The reason for the failure is that the DROP TEMPORARY TABLE command which
gets generated on connection disconnect might not have reached the slave
and hence the temp table remains on the slave.

Fix:
===
On master, upon disconnect, wait till connection is completely gone.  Then
ensure that DROP TEMPORARY table statement is available in the binary log.
Sync the slave with master and check that temporary table count is zero on
slave. Fixed a typo in test name.
