MTR's internal check of the test case 'main.upgrade_MDEV-19650' failed.

This means that the test case does not preserve the state that existed

before the test case was executed.  Most likely the test case did not

do a proper clean-up. It could also be caused by the previous test run

by this thread, if the server wasn't restarted.

This is the diff of the states of the servers before and after the

test case was executed:
