Add unit tests

[MrPetovan]

Since this looks like a Dependency Injection-compliant projects, targeted unit tests should be easy to add, right?

hui .. sounds great :-D

We already introduced one functional test here. So we can now differ between unit-test (= mocking around) and functional-test (= using the App as a whole).

This is something, which we are currently (badly) mixing at Friendica :-) :-) .. So good work with this repo @MrPetovan :-) :-)

Ha, you're right, it was included in the Slim skeleton project.
