refactor for independent test dirs (#7)

* make it so that the actual tests can be moved anywhere, for example in abra recipe repos
-> major refactoring with pytest test discovery magic

* create RUNNER_DICT dynamically with importlib
-> none of the tests are hardcoded, more tests can be added by placing a folder

* autoload fixtures with pytest plugins

* add URL fixture to navigate on web pages. Includes url parser based on python urllib to generate correct links

* fix nextcloud setups and tests

*  add email groundwork with imbox

-This file can be used to define fixtures thate are then used by other tests which
-depend on [demo]. For this to work
-
-1. the Runner class of the other test needs to define the depencency as seen
-   by referencing RunnerDemo in the dependencies list:
-
-from src.tests_demo.runner_demo import RunnerDemo
-
-class RunnerOther(Runner):
-    dependencies = [RunnerDemo]
-
-
-2. the specific tests that rely on these fixtures need to import the fixtures.
-   To globally import for all tests in 'other', the import should be done in conftest:
-
-in 'conftest.py' in 'test_other' dir:
-from src.tests_demo.fixtures_demo import demo_fixture
