Auth tests are failing about hydrus

[alohamora]

@xadahiya I checked with the codebase...the assertion error is because we have set up authentication for all the endpoints in api. with set_authentication(self.app, True): at line 55 in test_auth.py.
Hence it shall always give a response with status code 401.
So should I remove the authentication for the tests or shall I change the assertion to
assert response_get.status_code == 401

Try reverting to before #88 and then running the tests.

As far as I know no major changes other than that were made.

I reverted to before #88 but the tests were still failing.
But instead I changed the encoding format of the authentication header as follows:
self.auth_header = {"Authorization": "Basic " + b64encode(b"1:test").decode("ascii")}
and the byte string generated in the auth header matched with that generated while requesting through a web browser i.e. MTp0ZXN0 and then all the tests were passing.
@xadahiya @chrizandr comments on this approach??

@alohamora this is fine, create a PR. This is actually how authentication works now. Nice work 👎

Fixed in #115
