Example Scene in examples uses the wrong rig name, which causes duplication with latest XRTK

XRTK - Mixed Reality Toolkit Bug Report

Describe the bug

If you add the examples to a clean project using the latest XRTK, when the Example "Base Scene" is loaded it causes the Camera Rig to be regenerated, which gets mixed results.

The Rig should be updated to the latest for conformity.

To Reproduce

1. Create a new XRTK app using core / sdk
2. Import Examples in to project
3. Open "BaseScene"
4. Check rig (Observe called MixedRealityPlayspace)
5. Touch XRTK config
6. Check scene

Expected behavior

The rig should already be using the latest rig and not cause error

Actual behavior

Different things happen at different times, but either:

• The rig is duplicated and two rigs are present, old and new
• Rig is deleted
• Rig is renamed but errors occur
• (occasionally) it works as expected.
