I could not reproduce reported assertion. However, I could
reporoduce test failure because missing wait_condition
and error in test case. Added missing wait_condition and
fixed error in test case to make test stable.

Problem was that total order isolation (TOI) is started before
we know sequence implementing storage engine. This led to
situation where table implementing persistent storate
for sequence in case of MyISAM was created on applier causing
errors later in test execution.
Therefore, in both CREATE SEQUENCE and ALTER TABLE to implementing
persistent storage we need to check implementing storage engine
after open_tables and this check must be done in both master
and applier, because if implementing storage engine is MyISAM
it does not support rollback.
Added tests to make sure that if sequence implementing storage
engine is MyISAM or we try to alter it to MyISAM user gets error
and changes are not replicated.
