*: Run update-copyright.py

The 2012 start date for the new test_*.py files is because --follow
considers them descendants of __init__.py:

  $ git --version
  git version 2.16.1
  $ git log --oneline --stat --follow -2 pyassuan/test_common.py
  1c19d38 *: Drop nose dependency

   pyassuan/__init__.py | 2 +-

but that doesn't seem like a big enough issue to be worth fixing.
