VR fix for different avatar scales.

Browse source 
Previously, if the avatar scale wasn't 1, the body and viewpoint would given the wrong vertical position in some situations, eg: getting up from click-to-sit; changing the 'Allow my avatar to stand' setting.
The avatar scale was being taken into account where it shouldn't have in MyAvatar::deriveBodyFromHMDSensor.
The bug started in 8b839fe71b ("VR fixes for different user heights and avatar scales".
Repro:
1. Set 'Allow my avatar to stand: Always'
2. Reduce the avatar scale to the minumum.
3. Set 'Allow my avatar to stand: When I stand'
4. Previously, the viewpoint would suddenly be below the floor.
