[FIX] project: use user right on portal task

The search on project were done as sudo with a domain matching the
"project_task_rule_portal" rule. This commits remove the sudo call
and corresponding domains.

This replace lpe's fix b8fe404e, and user connected to portal to see
his tasks, avoiding an error during crawling tests:

Error use case:
User try to access a task list from /my/projects with a filter on a project.
The project filter does not exist in task list since the rules applied are for
portal user -> an error is raised

Now, project list on /my/projects and the filter available on /my/tasks should
be the same.
