php-horde-mime review request

[Bryce Harrington]

Can someone give a quick review of this bugfix for php-horde-mime?

These are really simple fixes that I've verified in lxc solve the dep8
failure.  This isn't blocking the php transition but will close off the
last php-horde* package (for now).  It's essentially the same fix as the
one for php-horde-text-filter I did last week, so if there are any
issues with this fix they'll be applicable to that one too.

Thanks,
Bryce
