[imp] imp cvs head viewing messages with html error

[Vijay Mahrra]

I had a bug in IMP-CVS HEAD

Warning: Invalid argument supplied for foreach() in
/data/apache/vhosts/www.mahrra.com/htdocs/horde/imp/lib/Identity/imp.php
on line 311

when viewing messages which had a HTML attachment, not sure why exactly
but changing the offending line seemed to work:
