[FIX] mail: no view edit on forum link in notif

When sending notification from the frontend, if a template is rendered
for it and the user has the group "website.group_website_publisher" he
will get inherit_branding adding on elements things like:

  data-oe-id="42" data-oe-model="ir.ui.view" data-oe-field="arch"

but the chatter system has feature automatically redirecting an element
that have attribute "data-oe-id": this caused for example that a
link notification towards the forum would instead be redirecting to
editing the view of the notification.

This fix distinguish the inherit_branding in the chatter feature and
ignore them.
