[ADD] test_inherits_depends: new test module

This commit adds a test to test the scenario fixed in the parent commit.

Creating a new test module is necessary as the bug is only revealed when the
current module is different than the model._original_module (cf c9837ac5dcb)

Before that commit, was failing only the second search of
test_ir_model_data_inherits_depends.
Add other test to avoid regression of the bugs corrected at 574f4c3d and c9837ac

closes odoo/odoo#30116
