This commit effectively makes workspace switching useless as far as the active scene layer goes. The functions from the scene layer API to get the correct scene layer from "context" were a placeholder to be addressed by the workspace commit. When workspace was merged, however G.main was used as a replacement to pass the correct argument for the functions. As it turned out (surprise!) this leads to crash on render preview.
