Start dapp directly from metamask-ui.spec.js (#11299)

The dapp is now started directly from the `metamask-ui.spec.js` test
module. This makes it easier to run independently, and brings it in-
line with our other E2E tests.

The `--no-timeouts` flag is now used as well, rather than setting the
timeout to `0` within the test. This also brings it in-line with our
other tests.

Mainly this was done to facilitate further refactors which will come in
later PRs.
