Bug when editing a collection percentage in the impact ranking and its projects in the overall ranking

[mmahdigh]

How to reproduce:

1- Edit the percentages of some projects in a collection on the overall ranking page and save
2- Edit the share of the collection in the impact ranking (poll/root/ranking)
3- Check the invalid state in the overall ranking page

Ran into this a few times in testing, in several locations. Can edit correctly in very specific areas, but not all allocations.

notes:

• In initial ranking changes, I can't seem to make a change and get a valid value. Anytime a number is manually adjusted, I get the "invalid value!" error instead of the "save" button.
• Editing on the rankings page for anything above individual project allocations gives an "invalid value!" error. Changing project allocations correctly calculates the allocation changes for the rest of the group.
• (at the project level) Locking projects also allows the correct calculations to be saved, and saving works properly with changed allocations remaining after the save from the Rankings page"
