Unit-test not working - refactor and split

[TomasKulhanek]

Unit-test are not working. This prevents from properly test potential upgrade to Python 3 and Django and other libraries/frameworks. Executing manage.py test fails on auth failed

• [x] refactor
• [x] split proper independent unit test from integration tests which needs properly configured external services like b2access etc. - consider to remove integration tests from automatic unit tests of CI

test authentication fails for testcases

user = django.contrib.auth.authenticate(email=self.email,password=self.password)

fails internally on

Unable to display children:Error resolving variables Traceback (most recent call last):
  File "/home/vagrant/py3/lib64/python3.6/site-packages/django/contrib/auth/__init__.py", line 68, in authenticate
    inspect.getcallargs(backend.authenticate, request, **credentials)
  File "/usr/lib64/python3.6/inspect.py", line 1344, in getcallargs
    (f_name, kw))
TypeError: authenticate() got multiple values for argument 'email'

cause is that the position argument is expected to be email, and set 'None' by default. Second 'email' named argument is provided with value. Workaround (fix):

user = django.contrib.auth.authenticate(self.email,password=self.password)

Fixed by major refactor/upgrade and update
