* Remove the test-pre-setup.js file (and all usages). This file is required only if a tests uses HTML imports (and HTML import polyfill). * Remove all duplicated <script ...>/import '...' blocks. These duplicates were introduced by polymer-modulizer and can be removed. Change-Id: I005afb9b0d3882eb09b6ebb2dcdd7793700251b4
