settings-org: Hide image upload button if user no longer admin.

Adds hiding any elements with the `image_upload_button` class in
the organization profile (icon and logos) to the live updates in
`settings_org.maybe_disable_widgets`, so that any role changes
that remove admin permissions will update these images so that
they no longer appear able to be updated / deleted.
