Switch to the nose unit testing framework

The nose unit testing framework has some nice advantages over the
unittest standard library. As it is compatibly anyway I have added
it to the PIP requirements. Unit tests are now run with nosetests.

Add failing test for RLP GDI dataset patch

Currently, the RLP data with group identifier gdi-rp are not harvested.
This is because we are currently filter all non-dataset packages. These
packages, however, can safely be added. Hence, I have added a failing
unit test to test the behavior. The next commit will implement the
patch.
