Steps to reproduce:

1. Open RenderDoc
2. In "Launch Application", specify the editor executable
3. Click "Launch"
4. Create a new project or open an existing one
5. Notice RenderDoc disconnected beause Unity restarted itself

This breaks all workflows relating to shader debugging, and happens with other tools too. These tools depend on hooking the application as it starts, so they need to be the ones that start the process.

Workaround: use -debugHub cmd line parameter to launch the editor.
