getNextPageParam throws an error when setting the data for an infinite query to empty lists for pages & pageParams

[soorria]

Describe the bug

[!note] not sure if this is a bug, or me doing something i shouldn't be

When I setQueryData for an infinite query to

{
	params: [],
	pageParams: []
}

getNextPageParams throws a TypeError because the lastPage argument is undefined

Steps to reproduce
