Remove loading of thumbnail in the image provider
* Removed the load of the thumbnail from the local and remote image provider as they shall provide the image, not the thumbnail. The thumbnail gets provided by the thumbnail provider.
* The thumbnail provider is used as the loadingBuilder and the image provider as the imageProvider. Therefore loading the thumbnail in the image provider loads it a second time which is completely redundant, uses precious time and yields no results.
