The retryer lives above the fetchFn, and it re-runs the fetchFn whenever a retry happens. Usually, the fetchFn is a thin wrapper around the actual queryFn passed by the user. However, for infinite queries, it fetches all pages in a loop. The retryer breaks out of this loop if an error occurs on e.g. the second page, and then retries by running the fetchFn - which will re-set the loop This fix hoists the currentPage counter out of the fetchFn - into the closure created by onFetch. The outer closure is created from running `query.fetch` once, so it won't be re-set between retries. The fix also re-writes the fetch loop to always take the `currentPage` into account, where it was previously treating the first page differently
