solved issue where sometimes satelliteItem contains only 2 layers

Browse Source 
Normally 3 layers 0: ndvi, 1: wdvi, 2: natural. In some cases only 2 layers: 0: wdvi, 1: natural. Which caused error when requesting statistics.
This happened for example for cropfieldItem.Code ‘e08d71bd92334dbab9e645ad6e72da63’
