projman #6456 [Cost table] Wrongly generated with several resources on a task [open]

When several resources with the same role (because we know projman can't deal with several roles on the same task) are working on a task, when you generate the cost table, you will have for this task:

Name | resource1 load | resource2 load | ... | cost

instead of:

Name | role load | cost

(role load = sum of resources load)
