Multi-query seems to not update cache for boolean value.

I have a storage item:

map T:Account => bool

I use a .multi query to fetch the boolean value for all the members. This multi-query seems to update when the value goes from false -> true, but does not update when going from true -> false.

(It may be relevant to note that we never actually store false, we just remove the storage item, but it should return false on default).

You can see the behavior here with inline comments:

The image shows:

• Initially both users are suspended ([true, true]), (correct)
• We un-suspend one of them
• A new .multi query still returns [true, true], (incorrect)
• If you query the value of the un-suspended member separately, you get false (correct)
• Then if you multi-query again, you get the correct result of [false, true]. (correct)

Not this issue does not appear when going from false -> true. Only true -> false.

In polkadot-js stuff, we generally stay about from the above hooks when dealing with anything UI. In cases where it is re-usable and especially when it is useful to others, we move them to derives where we use RxJs.

For instance, the logic for the society member retrieval - https://github.com/polkadot-js/api/blob/master/packages/api-derive/src/society/member.ts#L23 (Still early, but should give through the concept of the splits employed there)

Can also ve done with the promise-specific api.combineLatest (which basically does what combineLatest does, with subscriptions and unsubscribes so it updates and the status changes)
