[9.x] Fix withoutVite

[iamgergo]

This PR fixes the withoutVite method.

---

With the latest release some Vite methods were added, however currently they are not compatible with the withoutVite testing method.

For example in an app.blade.php:

    {{
        Vite::withEntryPoints('resources/js/app.js')
            ->useBuildDirectory('vendor/package-name/build')
            ->useHotFile(public_path('vendor/package-name/hot'))
    }}

The following error is coming up:

Error: Call to a member function useBuildDirectory() on string in ...

The methods that are returning other value type than a string for example $this must be defined. Also, the __toString is added to the anonymus class to make sure blade can render it.

---

I was not sure how to test it since no other tests were added to the similar fake methods.

I opened the PR for the very first fix.

I think that it'd be much better if an instance of $this is returned from __call. Then the __toString() can take on the responsibility for rendering nothing in the blade views.

Thoughts?

Yes, I think you are right, it's a clever solution, thanks!

So, only __call, __invoke and __toString should stay, right? __call and __invoke should return with $this and __toString with ''. It is correct?

Okay, so for now, I leave it as is, because I'm not sure what side effects this refactoring would have.

Thank you!

Yup, that's correct.
