Fix DNS lookup hang / Remove Comodo Secure DNS

Browse Source 
Motivation:

- DNS lookup sometimes hang because it does not call
  tryToFinishResolve()
- Comodo Secure DNS handles negative lookup incorrectly.

Modifications:

- Add missing tryToFinishResolve()
- Remove Comodo Secure DNS servers from the list

Result

- DNS lookup does not hang on non-existent domain names
- More reliable DnsNameResolverTest
