Issue/Introduction

Task duration on main project remains incorrect even after dates update through autoschedule when a subproject task is moved from a far future date to a current date.

Steps to reproduce

1. Create a Main Project and Child project
2. On the Child Project, create a task
3. On the Main Project go to Tasks>>Actions>>Add Subprojects
4. Add the child project
5. Go to the child project and change the finish date to 06/02/2079.  The duration on the child and main project updates accordingly.
6. Since the 2079 date was incorrect, go back to the child project and change it back to the original date. 
7. The duration for the child project will update correctly.  But the finish date on the project stays at 6/2/2079 so the Main project will still show this date.
8. Autoschedule the main project and publish.  The dates change to the updated finish date on the task but the duration stays the same.
9. Go back to the child project.  The finish date is updated after autoscheduling the main project.
10. The the finish date on the child project is correct

Expected Results - The Main project finish date and duration is updated correctly.

Actual Results - The Main project finish date is updated correctly but the duration is not.
