* web_unsplash, website_forum
With [1], the access errors when a portal user were using the media
dialog got fixed. It also came with the unsplash capability for portal
user in the media dialog.
Still, there was a remaining problematic point: an internal user can't
upload an unsplash image in the backend through the media dialog. It
doesn't really make sense for an internal user to have less right than
the portal user.
This commit corrects that part.
Note that only unsplash images were problematic, not regular uploaded
image as the difference was that unsplash images attachment are saved
with an `url` property, which was triggering due to [2].
Finally, it was chosen to make that "bypass" more robust and opt in, so
forum and unsplash are allowing their use cases to go through, it's not
done in a generic way anymore.
Also fixing a small issue about the res_id not being sent when editing a
forum post, because it was assuming that the URL would end with the ID
which is not the case when you edit your answer.
