Corrected support for Ubuntu 18.04 Bionic. Ansible due to some bug was in other role incorrectly transforming docker repository entry treating it as a regular Debian/Ubuntu repository which led to 404's

Tried this role, then debobs.logrotate - logrotate was modifying the sources.list incorrectly using Ansible native mechanism and was stopping at "Update APT cache"
