Manila's post_test_hook runs tempest after
populating tempest.conf with the requisite
options, the results from tempest are saved
prior to performing some post tasks, including
deciding to run tests again with a different
configuration if necessary
(Ex: manila-tempest-minimal-dsvm-dummy). The
result is then replayed at the end of the gate
job so it can be reported to gerrit as a
SUCCESS or a FAILURE.
Fix the mis-aligned command that saves the
test execution status to replay later.
