Fix problem with resolving template lookups

Summary

When rundeck_projects variable contains "lookup('template', '...') and this variable is passed to loopthere is a problem with finding this templates. There is (probably) some bug when using loop andansible_search_path` list changes and there is missing path to playbook root templates.

Steps to reproduce

- debug:
    msg: "{{ ansible_search_path }}"

- debug:
    msg: "{{ item }}"
  loop:
    - "{{ ansible_search_path }}"

Expected behavior

Content of ansible_search_path should be the same.

Actual behavior

Something like TemplateNotFound error is thrown.

Possible fixes

Do not pass lookup to loops.
