Merge pull request #457 from SimonRichardson/ensure-charm-store-prefix

#457

The following PR ensures that all the URLs have the correct prefix, that
way when we come to implement the charm-hub deployment workflow we do
that without breaking the old tests.

Eventually the cs: (charm-store) will be removed, but whilst we're in
transition, we should still support it and the tests associated with
them.

The code is very mechanical and should show that a cs: prefix is
mandatory if the user wants to contact the charm-store.
