The total test case count in problem_mapping.js is not updated after new test cases have been added to a TSV file.

General issue: please see title.
Classification: buggy test framework code.
Repro: add a few test cases to any TSV file and look at the result shown by index.html. For example adding a few test cases with negative numbers to epijudge/test_data/primitive_divide.tsv will make index.html think you are failing the test even when you are actually passing all given test cases.
