D4497: tests: rewrite test-lrucachedict.py to use unittest

[indygreg (Gregory Szorc)]

Herald added a subscriber: mercurial-devel.
Herald added a reviewer: hg-reviewers.

REVISION SUMMARY
  This makes the code so much easier to test and debug.
  
  Along the way, I discovered a bug in copy(), which I kind of
  added test coverage for.
