email2trac bug

[Eric Pettersen]

The unique_attachment_names() function in email2trac is looking for the variable "filename" to be the string "None" when in fact it is the Python value None. I think this is happening because of a signature block in Ute Ermel's replies. It affected ticket #19718 multiple times.
