Fix multiple things in CI

Disable irmc virtual media test_prepare_instance_with_secure_boot
and test_clean_up_instance_with_secure_boot
Related-Bug: #2025424

Explicitly close out test connection
When creating a test database, we should follow the same
pattern we know to be good, where an orphaned handler is not
left in memory to close out a connection.
Change connection style in dbTestBase to mirror how we do
database connections so they close out when we are done
with them.

Change migrations timeout to be >60 seoncds
In local testing, I found the migrations tended to take an
average of 70 seconds. Granted, my test machine is old, and slow
but the performance is very similar to a busy cloud provider.
As such, increase the timeout to a larger value so we can enable
the double migration test again.
Also use BASE_TEST_TIMEOUT as time limit for unit tests, failing
hard if that's passed.
