test: remove obsolete domain test

test-microtask-queue-run-domain.js tests that the behavior of another
test, test-microtask-queue-run.js, is still consistent when the core
domain module is loaded.

This was needed because before the changes in #16222 were merged, the
core domain module would replace the function that would call nextTick
callbacks with a different implementation.

This is no longer the case, and therefore that test is no longer needed.
