image items should show the main image

[OriHoch]

reproduction

• open an image page (now that we have main image)
  • e.g.: http://test.dbs.bh.org.il/image/izhak-and-belkis-hannah-chohen-with-her-childs-in-borujerd-iran-1949

expected

• should show the main image

actual

• no main image
  

• backend API response does contain the main image url: http://devapi.dbs.bh.org.il/v1/item/image_izhak-and-belkis-hannah-chohen-with-her-childs-in-borujerd-iran-1949
