test plan:
- take the flat manifest attached to CNVS-13219 and find the <gradable>
tag
- add a points_possible attribute to it, for example
<gradable points_possible="101">
- import the manifest as a common cartridge
- the imported assignment should have the specified points possible
refs CNVS-13503
fixes CNVS-13576
