Use Laravel container on private Router - closes #77

closes #77

As the container parameter is nullable in Illuminate\Routing\Router's constructor, an empty container is assigned in its constructor when no container is provided.

Since laravel/framework#44339 introduced Illuminate/Routing/Contracts/CallableDispatcher, a router needs this interface bound to dispatch closure bound routes such as the ones registered here:

laravel-missing-page-redirector/src/MissingPageRouter.php

Lines 42 to 53 in ba2bc5f

	$this->router->get($missingUrl, function () use ($redirects, $missingUrl) {
	$redirectUrl = $this->determineRedirectUrl($redirects);
	$statusCode = $this->determineRedirectStatusCode($redirects);
	event(new RouteWasHit($redirectUrl, $missingUrl, $statusCode));
	return redirect()->to(
	$redirectUrl,
	$statusCode
	);
	})->where('wildcard', '.*');
	});

This PR

• Passes Laravel Container to the Router constructor in this package's Service Provider, so it has a container which knows how to build a CallableDispatcher instance.
