bitbake: toaster: Bug-fix pytest and Failed: Database access not allowed

Remove load and create build environment from tests/functional/functional_helpers
- Testcases in the FunctionalTestCase do not require a build process,
- Also marked setUpClass or class with pytest django_db, db ... not
  working, as declared above of file functional_helpers.py, The database access
  process runs as an external process, separate from the test case process
  and outside the context of pytest.
