Scoreboard (below_name) is displayed incorrectly

To reproduce this bug you'll need a second player to see how it looks on him:

1. Create scoreboard with displayname:
   /scoreboard objectives add test dummy "test"
2. Make it below name:
   /scoreboard objectives setdisplay below_name test
3. Look at the result on the second player
