[Renderer] Look for outputs that starts with RENDER_OUTPUTS

Requested by @lisa

The renderer should look for outputs that starts with "RENDER_OUTPUTS", so it also gets the ones named "RENDER_OUTPUTS (2)"

For it to look for anything starting with “RENDER_OUTPUTS” , so it would also find “RENDER_OUTPUTS (2)” The same as it does with “Matte_OUTPUTS” , it will also find “Matte_OUTPUTS (2)”
