[FIX] project: grouped by personal stages in kanban -> user == current user

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

- Go to project > My tasks
- Click on load More on the first column
- Nothing is loaded

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

The orm groups by stages for each stage where the user is
the current one or null
-> This returns a null stage when the left join has not match
   But we only want stages linked to the current user

Solution
========

When loading project kanban groups and isGroupedByPersonalStages is true:
Add the user_id to the domain

This is the same solution applied in saas-15.3
