Fixing librarian-ansible so it works!!

 - Move `resolve_with_librarian` to `#prepare_roles` function

 - Ensure roles in Ansiblefile are installed to sandbox roles path: `tmp_roles_dir`

Fix some issues with ansible install procedure

 - Fixed Ubuntu installs of ansible via PPA (Tested on 10.04 (lucid), 12.04 (precise), 13.10 (saucy), 14.04 (trusty))
