Roles in playbook-local collections in not working in Molecule 3.0.6 with ansible 2.10

Issue Type

• Bug report

Molecule and Ansible details

$ molecule --version
molecule 3.0.6
   ansible==2.10.0a3 python==3.7

Molecule installation method (one of):

• pip

Ansible installation method (one of):

• pip

Detail any linters or test runners used:

Entire configuration is here: https://github.com/geerlingguy/ansible-content-testing

1. Git clone that repo
2. Install Ansible 2.10 distribution: pip3 install --pre ansible>=2.10
3. Run molecule test (uses Docker to bring up a kind instance)

Desired Behavior

Roles that are in collections local to a playbook should be picked up and usable by Ansible.

See the example.one and example.two collections in the repository: https://github.com/geerlingguy/ansible-content-testing

Actual Behaviour

    TASK [Include a 'test' role from 'example.one' collection.] ********************
ERROR! the role 'example.one.test' was not found in community.kubernetes:ansible.legacy:/Users/jgeerling/Development/GitHub/ansible-content-testing/molecule/default/../../roles:/Users/jgeerling/.cache/molecule/ansible-content-testing/default/roles:/Users/jgeerling/Development/GitHub:/Users/jgeerling/.ansible/roles:/usr/share/ansible/roles:/etc/ansible/roles:/Users/jgeerling/Development/GitHub/ansible-content-testing/molecule/default/../..

The error appears to be in '/Users/jgeerling/Development/GitHub/ansible-content-testing/tasks/same-name-roles.yml': line 4, column 11, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  include_role:
    name: example.one.test
          ^ here

This started happening once 3.0.6 was released, and I believe the change in https://github.com/ansible-community/molecule/pull/2745 was what triggered the problem.

The molecule configuration is in the molecule subdirectory inside the ansible-content-testing repo.

Weird, with Ansible 2.9.10 installed I’m now getting:

--> Action: 'dependency'
ERROR! Unexpected Exception, this is probably a bug: cannot import name 'AnsibleCollectionLoader' from 'ansible.utils.collection_loader' (/usr/local/lib/python3.7/site-packages/ansible/utils/collection_loader/__init__.py)
    the full traceback was:

I think this was fixed with the latest versions as I was able to reproduce it.
