Idempotence test fail in handler not attributed to handler

[Perdu]

Prerequisites

• This was not already reported in the past (duplicate check)
• It does reproduce it with code from main branch (latest unreleased version)
• I include a minimal example for reproducing the bug
• The bug is not trivial, as for those a direct pull-request is preferred
• Running pip check does not report any conflicts
• I was able to reproduce the issue on a different machine
• The issue is not specific to any driver other than 'default' one

What happened

When a handler is not idempotent, molecule reports that the tasks failing the idempotence test is the task notifying the handler instead of the handler itself.

Example:

test.yml:

---
- name: 'Test task'
  command:
    cmd: echo "ok"
  notify: "some handler"

converge.yml

---
- name: Converge
  hosts: localhost
  gather_facts: false
  tasks:
    - name: Replace this task with one that validates your content
      import_tasks: '../../test.yml'

  handlers:
    - name: "some handler"
      command:
        cmd: echo "handler"

molecule test:

INFO Running default > idempotence

CRITICAL Idempotence test failed because of the following tasks:

• => Test task
• => Test task

-> "Test task" is reported twice, instead of "Test task" once and "some handler" once.
