Subject: [PATCH] [FIX] project: project grouped by stages now respects the
 pagination

Steps to reproduce
==================

- Open any project
- Create many project stages (80+)
- Switch to the list view
- Group by stage
- Switch to to next page
=> The pager keeps increasing

Cause of the issue
==================

`stage_id` has a group_expand: `_read_group_stage_ids`

This method is used to include empty stages in the result for the kanban
view, so that we can drag tasks to an empty stage.

Solution
========

Add a context key `project_kanban` and only add empty stages in that
case.
