ApiAnnotations : Empty context loses annotations

A type signature of the form

bar :: (   ) => a-> Bool

generates annotations for the ( ) => but the SrcSpan they are attached to is discarded so the annotations are not attached to the AST.

The discarding process happens in

mkHsForAllTy exp tvs (L _ []) ty = mk_forall_ty exp tvs ty

where the empty located context is discarded.
