Update some view tests in the tags, sources and linking apps
to use the test case classes provided by the common app.

Instead of inserting the path of the apps into the Python app,
the apps are now referenced by their full import path.
This app name claves with external or native Python libraries.
Example: Mayan statistics app vs. Python new statistics library.
Every app reference is now prepended with 'mayan.apps'.
Existing config.yml files need to be updated manually.
