Stub out entry points in LookupTorrentURLTestCase
Stub out entry points in LookupTorrentURLTestCase

Torrent URL lookup functions are registered via entry-points.

If the tests run in an environment where the production lookup function is
present, it will use that; not what we want for tests.

Instead, we should stubout entry-points so we have a mock URL lookup function.
