 The `cycle_key()` method will use an empty `dict` for session data if it
 had not previously been loaded. The docstring says the function is there
 specifically to avoid losing sesison data, and the behavior feels
 inconsistent. This won't be noticed on most sites, as the
 `AuthenticationMiddleware` accesses the session on every request. However,
 it did cause problems for me in unittests for some views.
