test: remove obsolete domain test
This is similar to the PR that was submitted and merged at https://github.com/nodejs/node/pull/23252, but for another test.
test-microtask-queue-integration-domain.js tests that the behavior of another test, test-microtask queue-integration.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.
