Remove Exclamation (recalculation) mark from completed projects.

The exclamation point shows on all projects, including completed projects, when a change is made system wide. This is because all projects get flagged for recalculation due to a system wide changed. Then, when the system gets to the completed ones, it will check setting 9.4 "Recalculate revenue and cost for completed work items", then stop calculation on that project and move to the next project in need of re-calculation. However, if 9.4 is on, the exclamation mark should not show up on completed work items since it is confusing.
