This change fixes up a few test problems on release-3.0.x. These are:

We were still using old versions of the auth registry API, which caused some

  deprecation warnings.
One of those warnings was missing a trailing space on one of the concatenated

  lines, and mentioned the wrong method name.
The code to populate context['review_request_visit'] caused major problems

  if the viewing user was anonymous.
One of the tests for the action registry was broken by my recent markup

  changes.

There's still one failing test, which checks a query count when accessing the

review request resource. I haven't yet put any effort into tracking down how

this regressed.

Ran unit tests.
