async_hooks: ensure event after been emitted on runInAsyncScope

The exception handler user-defined will not automatically emit after
for the async resource.

Also removes a duplicated case
`test-emit-after-uncaught-exception-runInAsyncScope.js`
which is identical to test-emit-after-uncaught-exception.js.
