[FIX] project: fixes a traceback when opening project burndown chart

Before this commit, when a Project user opens the "Burndown Chart"
report from Project app, a traceback is occured due to an invalid
domain in the `ir.rule` for this report.

This commit fixes the issue by updating the domain since the `task_id`
field no longer exists on that report.
