Following the Flow upgrade, I was experimenting with the various codemods in flow-upgrade. I gave removeExplicitlyExactObjectTypeSyntax a try, since we have exact_by_default=true set in our .flowconfigs, and as such {} is an alias to {||}.
The codemod found a couple locations in this file. For the sake of consistency, I replaced them with {}, like we do elsewhere in our codebase.
Depends on D10087
