Corentin Wallez 43ef0a365b ValidationTest: Make custom device creation go through a virtual method 
Previously tests that needed to use a device that wasn't the default
device created a new one via a method that only supported customizing
extensions. Instead of adding a second function the device creation is
made completely customizable by querying the test's device via a
overridable method.

This heavily refactors the QuerySet tests to use the new methods
(previously they were using 3 different devices in the same fixture) but
loses a little bit of coverage of what happens when some query
operations are done with mixed devices.

This is required for a follow-up CL that adds tests for a device created
with the "disallow_unsafe_api" toggle that needs to be set on device
creation.
