fix: notifyOnNetworkStatusChange default to false (#61)

ApolloClient QueryManager mutates the watchQueryOptions passed in to watchQuery and makes this field false if it is undefined. This breaks the query caching mechanism because invalidateCachedObservableQuery is called with this mutated watchQueryOptions and so the cache key for options changes from "{}" to "{notifyOnNetworkStatusChange: false}" and the stale observableQuery is never removed from the cache.

Closes #59
