Before this commit, when the user removes a personal stage in Project
app and this personal stage has some tasks, the kanban model will reload
the data instead of delete the group. However, since the
`default_group_by` is personal stages then the group deleted stays
visible in the UI even if it is deleted for the backend side.
This commit flags the group deleted to avoid readd the empty group
when the reload is done to correctly remove the group in the UI.
