SECURITY: Don't pass a usable Pending Intent to 3rd parties.

Unfortunately the Settings app has super powers. We shouldn't let
untrusted 3rd party authenticators re-purpose those powers to their own
nefarious ends.  This means that we shouldn't pass along PendingIntents
that can have addressing information (component, action, category)
filled in by third parties.
