This adds a test for 511a53b3

Appeared in Opera with ModelAdmin.actions=None.

Thanks Tim Graham for the patch

Fixed #12685 - Ensure that deserialised model instances honor the same arguments as normal models.

Using `BaseCommand.options_list` makes Django use the legacy optparse
parser, which does not set the verbosity attribute correctly. Now the
verbosity argument is always cast to int. Regression in 85686386 (#19973).

Initial report and patch from blueyed.

Made URL application namespaces be set in the included URLconf and
instance namespaces in the call to include(). Deprecated other ways
to set application and instance namespaces.

Also moved it in the project template.
