[MC-57065] Filled map (model) missing

filled maps (the item itself) have a missing model (black/violet block in hand)

Environment

OS X , JAVA 8
Windows 8.1 , JAVA 7
Vanilla-Severs , JAVA 7

confirmed, when creating using empty map, has to be a second map

I didnt have that problem, when i get an empty map from my creative inventory and when i right click it to make a map, it just shows up like normal.

it's because it has to be a second map

Confirmed for 14w25a

Confirmed for maps with data value greater than 0
