Issue Summary

Change of dates in generated anchor sprints does not prompt to update the Allocations. Has flow-on impact to other areas.

Steps to Reproduce

1. Open Program Increments https://xyz.jiraalign.com/ProjectGrid
2. Create a new Program Increment by clicking on "Add New Program Increment"
3. Click on Tab "Sync Sprints"
4. Leave the duration as the default of 1 week (5)
5. Create Anchors
6. Change the dates on the Anchors created (because "I really wanted 2 weeks duration") to 2 week length
7. Save
8. Generate Team Iterations (or sync with Connector)
9. Click on cog icon next to an Anchor Sprint
10. Click on "Iteration Found"
11. Opens new window of https://xyz.jiraalign.com/IterationGrid called "Sprint List" with the Sprint flyaway panel opened.
12. Click on Members tab
13. Add a Member in, with Role Developer, Task Allocation = 100%
14. Save
15. Now open Program Increment Allocation Report https://xyz.jiraalign.com/ReleaseProductUserReport
16. Confirm you are in the correct Program Increment (for the Sprint)
17. View the Planned Hours for the Member that you added. 

Expected Results

Planned Hours for the Member will be 2 week's worth.

Actual Results

Planned Hours for the Member will only be one week's worth.

Workaround

Manual update. Which will work for small numbers of sprints, but not for larger numbers.
