Update tests to be used with aiida-optimade

Removed several test files that are not relevant for aiida-optimade.
Updated transformer tests to be applicable with AiidaTransformer.
Added an update of package version to invoke task for
/tests/test_config.json.

Note: Keeping test_middleware.py for now, since a new middleware may be
added in aiidateam#72.
