voidUpdates the stored data of the query list, and resets the dirty flag to false, so that
on change detection, it will not notify of changes to the queries, unless a new change
occurs.

((value: T) => unknown) | undefinedOptional function for extracting stable object identity from a value
in the array. This function is executed for each element of the query result list while
comparing current query list with the new one (provided as a first argument of the reset
function) to detect if the lists are different. If the function is not provided, elements
are compared as is (without any pre-processing).
