Moving \Symfony\Component\HttpFoundation\File\File instead of copying

[nadrshin]

Hi. In my project resolution of uploaded image changes after form submiting. As a result, сlass of image changes from \Symfony\Component\HttpFoundation\File\UploadedFile to \Symfony\Component\HttpFoundation\File\File. This bundle moves \Symfony\Component\HttpFoundation\File\UploadedFile objects and copies \Symfony\Component\HttpFoundation\File\File objects. After copying I nedd to delete files manually. Can you add configuration's setting to force movement all types of objects? Thanks.
