models: fix From header in mbox view

The From header in mbox view was corrupt for patch submitters with non-ASCII
characters in their names. RFC 2822 requires to retain the mail as ASCII in
braces '<' and '>' while the name should be coded. Before we coded the whole
string which led to some MUA misinterpret the From header (while git could
manage it).
Fix this by coding just the name and let the email untouched.
