Subject: [PATCH] [FIX] project: hide empty stages when user perform subtask
 action

Step:
  - Install project app
  - Activated  Task Dependencies
  - Create project and task
  - Add sub-task
  - Click sub-task action

issue:
    In the commit below we have passed the default_project reference so we get the
   current project stage.
Fix:
   we pass 'subtask_action' context to subtask action and we checked that context
   in _read_group_stage_ids method if subtask_action context is found then we will not
   fetch project's stages.
