Subject: [PATCH] Require `pim:storage` predicate if WebID is in agent's
 storage

Following the discussion in https://github.com/solid/specification/pull/772 - this PR requires that WebID's conforming to the Solid WebID profile use `pim:storage` to advertise the storage in which a WebID is contained, if the WebID is contained in Solid Storage.

The goal of this is to prevent the majority of client applications from needing to implement discovery of storages using link headers.
