Offline exchange: separate queries on same nullable object causes infinite network requests

Describe the bug

There is an edge case which causes the offlineExchange to infinitely send network request.

This occurs when calling multiple useQuery hooks with different queries for different data on the same nullable object. Additionally the bug only occurs when the api returns null for the object but does not occur if the root data is null

This bug only occurs when using the offlineExchange.

Please see the repro source code and server source code for further context. Client: https://github.com/seanaye/urql-offline-repro Server: https://github.com/seanaye/api-repro/tree/master
