ZoneJS is no longer loaded as an UMD, but instead is included as part

Previously, when we did not bundle tests, we also had the jasmine
default timeout increased to 15000ms. This commit re-introduces this
increased timeout by also maintaining a custom test init file for the
legacy saucelab jobs. This is desirable as all of the Saucelabs test
code is local in the `tools/legacy-saucelabs` folder.
