The Chromecast reports supporting IndexedDB but whenever an insert command was performed, the operation would hang indefinitely. This change introduces a pollyfill for the Chromecast that will remove the indexed db reference which will have DBEngine's "is supported" behavior to report no support. Alone this change would not stop the tests from running, so the DBEngine tests had to be updated to first check that the DEngine is supported on the active platform.
