Remove retain call from useBackgroundQuery to allow for auto disposal

[jerelmiller]

Thanks to the work in #11412, we no longer need to retain the queryRef produced by useBackgroundQuery since this is handled in useReadQuery for us. This means that a queryRef not consumed by useReadQuery within the given autoDisposeTimeoutMs will now be auto disposed, removing the need for the query to hang out as active while not used. #11412 enabled the ability to auto resubscribe to a disposed queryRef, so when the queryRef is consumed after it has been disposed, it will automatically resubscribe.

I'd like to see one more test, but generally approved :)

Maybe add one more test with a "natural dispose after being mounted with useReadQuery"
useBackgroundQuery -> mount useReadQuery -> unmount useReadQuery -> make sure it's disposed -> mount useReadQuery -> make sure it resubscribes
