Call to a member function arg_range() on null in _calendar_views_track_current_date()

Problem/Motivation

When upgrading from 1.0.0-beta2 to 1.0.0-beta3 we are having two issues:

• The pager is terribly malformed
• When a user clicks on the "next" arrow, they get "Call to a member function arg_range() on null in _calendar_views_track_current_date()"

I have not had time to fully investigate where the problem is specifically. I will try to flesh this out next week sometime.
