[TASK] Tests: Skip some FAL tests

While the FAL tests were already streamlined and simplified a lot,
the ResourceStorageTest class is still a mixture of functional and
unit test that involves heavy set up code and still does not mock
dependencies properly.
This test class needs a rewrite and a clean separation of units
together with a number of working functional tests to be of any use.
For now, all tests that rely on initialized database are skipped and
marked as TODO.
