- fixed some warning messages (language and subscription which was not needed)
https://github.com/openpeer/opios/issues/61

- Fix: finder was not realizing it's transport was shutdown (so it didn't self-destruct)
- Fix: split finder creation from finder DNS lookup as when there are no more finder servers available from DNS it fetch a new set of finders but it wasn't doing so because finder was already created but created finder was waiting for more finder DNS entries
