Use better workaround ofr getting scene layer for Derivedmesh's mask

This replaces access to the first scene layer (which was wrong) with a linear
lookup of scene layer by it's active index.

This seems to be a better temporary solution to have things working for until
we've got proper workspace, depsgraph and it's per-layer storage in place.
