mail: pass in addr to _addressencode() in bytes

_addressencode() doesn't process a unicode addr well. For example,
acc.encode('ascii') would raise UnicodeEncodeError if acc was a unicode.

This patch temporarily restores the pre-952bf3c948f0 _addressencode().
Several tests would be broken on Python 3.
