test: update test-domain-uncaught-exception.js

file: test/parallel/test-domain-uncaught-exception.js
1. There are three setTimeout() in the file and they do not specify a
duration (the second argument), so I change them to setImmediate()
instead.
2. There are four callbacks that take an argument called `err` but that
argument is never used, so I removed them.
