Fix quicksand interaction with HTTP GET prefilling in ApplicationSearch
Summary:
Fixes T10196. This is a weird interaction and this might not be the best long-term fix, but just get it working OK for now.
General problem is that Quicksand doesn't currently use GET for requests. This is a very unusual case where the method is relevant. In the future, I might change Quicksand to use GET.
Test Plan: Clicked "Open Tasks" with Quicksand active, got a results list.
