VRTemplate: Easy to clip through walls in HMD Locomotion map

When teleporting in the HMD Locomotion map, the player is able to teleport halfway through walls and objects. The teleport circle does not have a "Buffer" to prevent it from going into the BSP's around the area similar to the one for the MotionControllers map, which prevents this.

1. Open Ue4Editor.exe
2. Create a new blueprint VR template
3. Open the HMD Locomotion map
4. Play in VR-Preview
5. Teleport to a nearby wall

Expected Result: The player should be right beside the wall

Outcome: The player is able to teleport half-into the wall, resulting in clipping
