Add tests for kfet views.

kfet.tests.testcases embed mixins for TestCase:
- TestCaseMixin provides assertion helpers,
- ViewTestCaseMixin provides a few basic tests, which are common to
every view.

kfet.tests.utils provides helpers for users and permissions management.

Each kfet view get a testcase (at least very basic) in
kfet.tests.test_views.
