Icon unrefs

[Soeren Sandmann <sandmann daimi au dk>]

If you install Nautilus HEAD with a 2.4 control center, you of course
get broken icons, but you also get a CRITICAL error when the file
model tries to unref a NULL pointer returned from
nautilus-icon-factory. It can return NULL when the caller doesn't want
the default icon.
