Reactivity based on page store since 2.15.2

[Epoxide]

Just wanted to share a change since this commit.

If code existed before that was reactive to the page store and an effect was to always use goto it will trigger the reactivity in an infinite loop. Previously it was possible to use something like the following without triggering this behaviour:

$: someFunction($page.url.searchParams)

function someFunction(searchParams: URLSearchParams) {
  [...]
  goto(`?${searchParams.toString()}`)
}

If goto did not need to navigate due the search params being the same as the current page URL it would not trigger a change to the page store and would subsequently not trigger the reactivity and another call to goto. After the previously mentioned commit was added, the behaviour changed and the reactivity would always trigger a call to goto, creating an infinite navigation loop. It is now required to check if the search params of the current page are different from the ones that we want to navigate to are. If this is done an unnecessary call to goto will no longer be made and loop will never be entered.
