Reference Space Type is "viewer" in the frame the session start, instead of the proper one

[signorpipo]

If I set the space type to "local floor", the emulator does actually set it as local floor, but only the frame after the session started (or so).

U can check this by simply logging the space type on session start.

On a real headset, the space type will be the proper on session start already.

This make it so I have to add special cases for the emulator.
