* Add `--leave-running` flag to E2E test script The `--leave-running` flag has been added to the E2E test runner. This ensures the browser, ganache, and everything else stays running upon test failure. This is useful for local debugging, for investigating what state the extension was in when it failed. * Add `--leave-running` support to `metamask-ui.spec.js`
