Fix dependency injection to support lumen

[Kuodster]

Hello.

The current application dependency for the Migrator class is using a non-existent class in Lumen framework.

DragonCode\LaravelActions\Services\Migrator::__construct(): Argument #5 ($laravel) must be of type Illuminate\Contracts\Foundation\Application, Laravel\Lumen\Application given

Lumen and Laravel applications both implement Illuminate\Contracts\Container\Container interface, which is the one used to provide the call() method used by the package.
