Title: Change/fix memoization on hit assignments

Sorry this isn't represented with a test, more or a less a hotfix.

The problem was that calling ```.assigments(status: "Approved")``` on a Hit object would memoize the approved ones. But when you called ```.assignments(status: "Rejected")``` it would return assignments that were approved because of the or equals.

This fixes that problem that I introduced. My bad!
