Simplify list logic further to prevent misuse (#3334)

* simplify list logic further

more simplification

simplify by removing `isEmpty`

use `isFetchingNextPage` everywhere for clarity

change `isFetching` to `isFetchingNextPage` for clarity

remove some useless `useMemo`s

move `renderItem` and `keyExtractor` out of component

* clean bundle size check

* update deploy

* adjust

* adjust

* one test

* try now

* test it

* done
