Player hosting LAN world has default "Alex" skin

So, when I create a LAN world, my skin loads for me, but not the people joining.

What I expected to happen was...:
I expected my skin to load normally on my friend's screen

What actually happened was...:
I donned the "Alex" skin on the other player's screen

Steps to Reproduce:
1. Create a LAN world
2. Have someone join
