Avatar Blocks View in A-Frame Camera Implementation

[EricEisaman]

Hello Nikolay. The Avatar blocks the view when moving backwards. I initially thought it was a backface rendering issue until I realized that the camera was moving completely behind the avatar when going backwards. Setting the avatar scale to [2, 2, 2] seems to fix the issue. If you wish I can make a pull request to set the initial avatar scale to [2, 2, 2].
