imageWidth/imageHeight filters not available on cold cache

Winter CMS

Description

Twig filters | imageWidth and | imageHeight are not working until the resized image is generated (on cold cache) as they fail to manage /resizer/* url resource.

When the filter are applied to a /resizer/* resource, ImageResizer::filterGetDimensions() should calculate and return valid values (using the stored configuration?).

Will this change be backwards-compatible?

No breaking changes expected.

@matteotrubini any ideas for an implementation for this?
