The detail page of a link only displays the form if the link is editable
for the logged in user.
Therefore, it's not necessary to disable the input fields within the
form if the link isn't editable.

Even in dev mode, the user `tagged-devices` should not be
reported as existing user.
This allows editing & deleting links owned by `taggged-devices`
in dev mode.

It should be possible to delete links owned by non-existing users
(tagged-devices or deleted) in the same ways as it's possible
to edit these links.
