In the project.task model, the method _get_all_subtasks allows to get
all the subtasks linked to a recordset (recursively). This method uses
the method _get_subtask_ids_per_task_id that retrieves all subtasks ids
for each task record in the recordset using a sql query to optimize
performances (see odoo/odoo#117624).
This commit adds an additional WHERE clause in this request to avoid
looking for subtasks in records that have no parent_id set. On top of
that, a unit test is added for both methods.
