Use ansible_facts not default variables

[jochen314]

This fixes #280

[freemanjp]

@jochen314 thanks for the PR (I had no idea this was a thing Ansible did). But can you update one (not all) of the Molecule test scenarios to include inject_facts_as_vars: no to test this:

e.g. Update https://github.com/gantsign/ansible-role-intellij/blob/master/molecule/ultimate/molecule.yml:

provisioner:
  name: ansible
  config_options:
    defaults:
      inject_facts_as_vars: no

@jochen314 you can find your fix in version 6.11.0 of this role.
