Resolve #2225
Summary
This addresses a regression from #2189 where a mutation's operation is compared to filter results.
Such a comparison will always fail in the presence of cache exchanges that create new operations to update
the document of the operation (or variables)
Instead, we can introduce a stand-in identity object for the mutation instead and use that to compare.
This isn't a final resolution of the issue but a quick workaround.
