py3: use email.utils module instead of email.Utils
On py2:
>>> import email
>>> import email.utils as eutil
>>> email.Utils.parseaddr is eutil.parseaddr
True
>>> email.Utils.formatdate is eutil.formatdate
True
email.Utils is not present on Python 3.

"""test behavior of propertycache and unfiltered propertycache
The repoview overlay is quite complex. We test the behavior of

regression."""
