Remove testing and debug code from rdflib

This patch removes code from `rdflib/` that does not seem like it belongs
in `rdflib/`, most of it is related to doctest, some of it belongs in
`test/` and was moved to `test/test_misc/test_collection.py`, and yet
more of it seems to just be there for debugging purposes, though it
would possibly be better to put that in a separate place if it is needed
again or to debug using tests if possible.

Other changes:
- Removed an invocation of `rdflib.util.test` from `test_util.py`. This
  seems like an attempt to invoke doctest however pytest takes care of
  that so this is not needed.
