Prepared migration of unit tests from "integration" (running on device/emulator via android testing framwork) to actual unit tests via robolectric:
- migrated tests to JUnit4
- migrated most tests to robolectric within test project
- added testing dependencies to app POM
Merge branch 'develop' into feature/Robolectric

Finished migrating of unit tests from "integration" (running on device/emulator via android testing framwork) to actual unit tests via robolectric.
All current tests can now be run as unit tests.

Deleted nusic.test as there currently are no real integration tests and the projects would have to be converted to maven anyway.
Merge branch 'feature/Robolectric' into develop
