include_role with passed variable defined by template fails

[Dmitriy Panteleyev]

I'm a bit confused how variables are defined when using `include_role`.  A basic example follows.

/play.yml

- hosts: localhost
  roles:
    - one

/roles/one/tasks/main.yml

---
- name: do a thing with another role
  include_role:
    name: two
  vars:
   passed_variable:
     - stuff: "{{ lookup('template', 'role_one_template.j2') }}"

/roles/one/templates/role_one_template_file.j2

bla bla bla bla
random bit of stuff
does not matter what

/roles/two/tasks/main.yml

---
- debug:
    var: passed_variable

My expectation is that role "one" will pull the template and pass the results of that lookup to role "two".  However, when running the play, I get first a warning, and then an error.  It seems as if the template lookup occurs in role "two".  So, what exactly is going on, and how do I fix it?

looking for "role_one_template.j2" at "/roles/two/templates/role_one_template.j2"
looking for "role_one_template.j2" at "/roles/two/role_one_template.j2"
looking for "role_one_template.j2" at "/templates/role_one_template.j2"
looking for "role_one_template.j2" at "/role_one_template.j2"
 [WARNING]: Unable to find 'role_one_template.j2' in expected paths (use -vvvvv to see paths)

The template does not exist.  You are using the wrong template file in your lookup call:

```

    - stuff: "{{ lookup('template', 'role_one_template.j2') }}"

```

However, you have indicated the file is actually named: /roles/one/templates/role_one_template_file.j2

Sorry, that was just a typo in my example.  The filenames all match.

Finally tracked the issue down to my misunderstanding of how lookup() works.
