Prevent ssrExchange().restoreData() from adding results to the exchange that have already been invalidated. This may happen when restoreData() is called repeatedly, e.g. per page. When a prior run has already invalidated an SSR result then the result is 'migrated' to the user's cacheExchange, which means that restoreData() should never attempt to re-add it again, by @kitten (See #1776)
⚠️ Fix accidental change in passive stale: true, where a cache-first operation issued by Graphcache wouldn't yield an affected query and update its result to reflect the loading state with stale: true. This is a regression from v2.1.0 and mostly becomes unexpected when cache.invalidate(...) is used, by @kitten (See #1755)
