Remote Functions: If query isn't used elsewhere, it gets re-fetched every time it's used in `.updates()`

[ottomated]

Describe the bug

If I have a form like this:

<form {...addTodo.enhance(async ({ data, submit }) => {
  await submit().updates(
    get_todos().withOverride((todos) => [...todos, { text: data.get('text') }])
  );
}}>

but for whatever reason get_todos() isn't currently being used elsewhere on the page (i.e. the todos component isn't mounted) the following issue happens:

1. SvelteKit calls create_remote_function
2. Cache miss - query_map doesn't contain get_todos()
3. SvelteKit initializes get_todos() and makes a fetch request to the endpoint
4. get_todos() gets cached
5. get_todos() gets immediately removed from the cache, because there are no references to it
6. Repeat steps 2-5, every time the form is submitted.
