Prevent duplicate role insertion into roles: (#50552) * Corner case in which import_role would add another instance of a role with the same signature into roles: when it already existed there. roles: - name: a tasks: - import_role: name=a would execute role 'a' 3 times instead of the intended 2 (x2 in roles: phase +1 in tasks:) * added tests 6 years ago			`- name: test that import_role adds one (just one) execution of the role`
