We were accidentally ignoring `node/routes` because we had "out"
instead of "/out" in `coveragePathIgnorePatterns` which caused
us to not collect coverage for those files. Now we do.
Inside registerServiceWorker, we were originally using the nullash coalescing
operator to check if options.base was null or undefined. However, I realized
this check is not necessary.
If you look at getOptions' return value, we return an object with a key "base"
which is of type "string". We get that value by calling resolveBase which always
returns a string.
As a result, we didn't need to check if options.base was null or undefined
because it never can be.
Remove the Mac directory copy instead of refactoring it since we've had
this for a long time now and I think it's safe to assume that users
running code-server on Mac don't have the old directory anymore.
