role without yml files isn't role

[torgiren]

This fixes false positive checks on roles. ex: I have some static files in my role (this are nagios static files), so i have role: nagios/tasks/main.yml nagios/files/static/commands/something.cfg nagios/files/static/templates/my_templates.cfg nagios/files/static/services/services.cfg

and ansigenome finds template folder in my static, and add role nagios-files-static to graph... this isn't role. So, I fixed it, but add conditional, that if folder contains yml file, that means that is role
