Removes code that updates JSON results for skipped tests after all tests are run
Removes code that updates JSON results for skipped tests after all tests are run

This code runs when no expectations file is passed. It makes sure that tests that
were actually skipped have 'SKIP' as its expected value. Changes to typ's runner.py
in a previous CL make sure that when a test is skipped through the command line or
when the test calls self.skipTest() and no test expectations file was passed to Typ,
then the expected field is set to 'SKIP'.
