In tests, convert assert statements to self.assert()

[sumit4613]

Convert all assert statements to use self.assert...().

Example:

drf-user/tests/test_views.py

Line 33 in ee2de49

assert User.objects.count() == 1

Convert the above assert statement like this

self.assertEqual(1, User.objects.count())

Please note that the expected value should be on the left and actual on right
expected == actual
