tests: Verify GParamSpecPool creation

Ensure that the fix in commit af024b6d7e7d3fbef23c1f7d1f7704fc90ac4fb1
works, by replicating what gobject-introspection does:

- initialise the default GTypeInterface from a GType without also
  initialising GObjectClass
  - install a property for the interface
- find the GParamSpec using g_object_interface_find_property()
