test_crud.py uses a different method to import the doc

[xadahiya]

I'm submitting a

• bug report.
• feature request.

Current Behaviour:

hydrus/tests/test_crud.py uses a different method to import the doc.

from hydrus.data import doc_parse
from hydrus.samples.doc_writer_sample import api_doc as doc

    def setUpClass(self):
        """Database setup before the CRUD tests."""
        self.doc = doc
        test_classes = doc_parse.get_classes(self.doc.generate())

Fix this and make the import format consistent across all the tests.

Expected Behaviour:

All tests should use the same format.

Steps to reproduce:

Compare test_crud.py with test_app.py and test_auth.py.
