useLazyLoadQuery holding onto old data

We have a single `useLazyLoadQuery` hook that gets passed new variables as you change screens in our app. When you revert to a previous set of variables, the data is served from memory and never triggers a refetch to the network. This is true even if the networkPolicy is set to `network-only`. We are unable to track down the root cause, but reverting back to `react-relay@0.0.0-experimental-c818bac3` makes the issue immediately disappear.
