Update web.php

[iliyaZelenko]

This solves the problem with API 404 response.

If you put the following code in routes/api.php it does not work:

Route::fallback(function() {
    return response()->json(['message' => 'Not Found!'], 404);
});

If no route is found, then there is the possibility to return an 404 error.
