tests.py - Don't skip cleanup anymore.

Don't skip cleaning up attribute values during tests.
Skipping the cleanup was done so that DeferringList
wouldn't be executed during tests.  But that is handled
better by checking if site.method=="LOCAL" instead.

Doing the cleaning makes the test output match the
real scraper output more closely.  Better for debugging.
Create administrative_agency dir and move MSPB scrapers.
