Testing lazy props

[JeroenGovers]

I added the method requestProp (name open for discussion 😉) to the AssertableInertia class which let you easy test LazyProps.

/** @test */
public function test_props(): void
{
    $this
        ->get('/')
        ->assertInertia(function (AssertableInertia $page) {
            $page->has('normalPropKey');
            $page->missing('lazyPropKey');

            $page->requestProp('lazyPropKey', function (AssertableInertia $page) {
                $page->where('lazyPropKey', '1');
            });
        });
}

The method uses the previous request, applies the X-Inertia-Partial-Component and X-Inertia-Partial-Data headers, which are automatically seeded and resends it. A convenient way for the tester, and they do not need to know the internal mechanics of Intertia. Which I found in #604.

Thanks for this! I've reworked it a bit in #738 as this was targeted at 0.x. I also didn't want to rely on the app environment and binding in the container. When the new PR is merged, I'll make sure to add you as a contributor!

@pascalbaljet it's great to hear that the new test helpers are now available in 2.x. I will definitely use them in my tests. You spoke of making me a contributor when the PR is merged. I would realy love that ☺️
