Fix for bug 199320 -- random composer crashes. Remove code that set the editor as a refCon on a controller which was created in JS, because it's unnecessary, and because the JS has no callbacks that allow it to null out the refCon when that editor is destroyed, leading to stale references which crash XPConnect. r=brade, sr=kin, a=asa.
