Possible bug in `initiate()` promise resolution timing

[markerikson]

While testing upsertQueryData, I was doing something like this:

const fetchRes = dispatch(post.initiate('3'))
const upsertRes = dispatch(upsert('post', '3', {obj}))

await upsertRes;
expect(data).toEqual(upsertedData)

await fetchRes
expect(data).toEqual(fetchedData)

including a queryFn that was supposed to wait some delay before resolving.

Except it never worked. when I added a bunch of logging, the upsert did indeed update the state first, then the fetch, but somehow the upsertRes promise never resolved until the fetch update was complete. I couldn't figure out if it was a problem with my test code, or the "running promises" logic.

This may be related to #2477 / #2481 in some way, or it could be a different promises bug.

Yeah... I think upsert promises need their completely independent handling there... drat.
