The short version is that, when `setup_databases` detects that two
databases are identical, it does `connection.settings_dict['NAME'] = ...`
instead of calling `connection.creation.set_as_test_mirror()`.
I'm going to attach a project that allows reproducing the issue.
(Unfortunately, we don't have a convenient way to test the test runner's
database creation features.)
If you set `DATABASES = DATABASES_POSTGRES` in the settings, the test
passes.
If you set `DATABASES = DATABASES_ORACLE` in the settings, the test fails
with `myapp.models.DoesNotExist: MyModel matching query does not exist.`.
