<!--- Verify first that your issue is not already reported on GitHub -->
<!--- Also test if the latest release and devel branch are affected too -->
<!--- Complete *all* sections as described, this form is processed automatically -->

##### SUMMARY
<!--- Explain the problem briefly below -->
To include tasks for handlers I have to specify full path instead of relative to the role's directory
Similar to: https://github.com/ansible/ansible/issues/19609

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
`lib/ansible/playbook/included_file.py`

##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes -->
```paste below
ansible 2.9.4
  config file = /srv/data/ansible-dev/ansible.cfg
  configured module search path = ['/home/spider/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /srv/app/prod/ansible/core/ansible-2.9/lib64/python3.6/site-packages/ansible
  executable location = /srv/app/prod/ansible/core/ansible-2.9/bin/ansible
  python version = 3.6.3 (default, Apr 10 2019, 14:37:36) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]


```

##### CONFIGURATION
<!--- Paste verbatim output from "ansible-config dump --only-changed" between quotes -->
```paste below

```

##### OS / ENVIRONMENT
<!--- Provide all relevant information below, e.g. target OS versions, network device firmware, etc. -->
RedHat 7

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
in role's handlers directory I have:

cat main.yml
<!--- Paste example playbooks or commands between quotes below -->
```yaml
---
# handlers file for sshd

- name: Include proper handlers for services
  include_tasks: "{{ ansible_distribution }}{{ ansible_distribution_major_version }}/handlers-services.yml"
  listen: 'Handle sshd services'
```
The full path works ok:

```yaml
---
# handlers file for sshd

- name: Include proper handlers for services
  include_tasks: "{{ role_path }}/handlers/{{ ansible_distribution }}{{ ansible_distribution_major_version }}/handlers-services.yml"
  listen: 'Handle sshd services'
```
<!--- HINT: You can paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
Tasks should be included from path relative to role

##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->
Include fails as ansible tries to include handlers-services.yml directly from playbook directory
<!--- Paste verbatim command output between quotes -->
```paste below
RUNNING HANDLER [sshd : Include proper handlers] ***************************************************************************************************************************************
fatal: [tpinsas03]: FAILED! => {"reason": "Could not find or access '/srv/data/ansible-dev/playbooks/RedHat7/handlers-services.yml' on the Ansible Controller."}
        to retry, use: --limit @/srv/data/ansible-dev/retry/cm.retry
