Avoid raising TypeError for missing *_last_id value in condition fields.
Review Request #8917 — Created April 27, 2017 and submitted
The value_from_datadict() method would raise a TypeError if the *_last_id value was missing from data. The code was expecting to catch KeyError, but was using data.get() instead of data[] and passing None to int().
Added test cases for empty data dictionary and missing *_last_id value. The new test cases fail before the change and all tests succeed after.
