Test lib/lp/registry/tests/../stories/foaf/xx-resetpassword-of-sso-account.txt fails if canonical-identity-provider absent

We could add some infrastructure to have certain tests run only when c-i-p is available, move the test to c-i-p or trim it so that it only shows that it's possible to start the password-reset workflow from launchpad.net.

Since the test was actually written to show that a user can request a password reset of a personless account from launchpad.net and the fact that the last step of resetting a password is already tested in c-i-p, we could safely trim the test without losing any test coverage. Or we might comment out the bits that depend on c-i-p until we can mark some tests to run only when it's available.

From a community developer's point of view, it would absolutely suck to have to remember a list of tests which always give false failures.
