Remove duplicate service worker test
This test exists in both WPT and the Chromium project tree. The WPT
version is slightly weaker because it accounts for a condition that is
not possible according to the latest version of the Service Workers
specification [1].
> # Install

> 17. Run the Update Registration State algorithm passing registration,

> 21. Invoke Try Activate with registration.
Due to step 20, worker activation does not occur until all prior tasks
(which includes microtasks such as the Promise handler microtask created
in the test's body) have executed.
Remove the conditional logic from the WPT version and remove the
Chromium test file. Explicitly un-register workers following test
completion.
