Brian Coca 4a89749dd5 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
