<pre>Tweak ServiceWorkers.SuspendServiceWorkerProcessBasedOnClientProcesses to find out source of timeout
https://bugs.webkit.org/show_bug.cgi?id=225770
Reviewed by Alexey Proskuryakov.
Wait for conditions with our own timeout so that the test fails with useful errors instead
of just a generic timeout. This just help us find out where in the test things go wrong.
