After placing a door, by hand, in the North or South direction, ```/testforblock``` doesn't properly detect the block state. Eg:

Place iron door by hand facing South and use ```/testforblock ~ ~ ~ iron_door 1``` is unable to see the door. However, if I use ```/setblock``` to place the door with the correct block state of 1 and then test there is no such issue.

There is also another related bug: the block state 1 and 17 show the door hinge on the same side when they should not be. Which is different from when the door is placed by hand.
