Reduce concurrency on frontend tests.

Currently our tests fail when attempting to run them locally. The reason
seems to be that, when concurrency is not set 1. All concurrently
running tests, except for 1. Have document.visibilityState === "hidden"
and document.hasFocus() === False. Which leads to failures with event
handling (and for the logic that directly interacts with the
visibilityState).

This is a temporary fix, which we will hopefully be able to remove once
the underlying issue is fixed in web-test-runner (or Chrome).
