Make final test pass(?)

Mock out the createClient method to return the same client, because
we've mocked the peg to always return that client, so if we let the
code make another one having still overridden the peg, everything becomes
cursed.

Also mock out the autodiscovery stuff rather than relying on fetch-mock.
