Remove obsolete Tentative 1.4 suite from debug runner https://screenshot-v2.corp.google.com/5lm6dv2klfr20 The 8 tests from the tentative 1.4 suite (Stories, Alice, Chess, Map Zoomer, Sheets, Départements, Dashboard, Filtering) are already the primary MotionMark suite in resources/runner/tests.js. Keeping them as a separate Tentative 1.4 suite in debug-runner/tests.js duplicates all 8 tests when opening developer.html. Change-Id: I8c08082f95d510016ded94f1769370cfeb17b9f0
