GHCJS.DOM.Document module conflicts with same in ghcjs-dom-jsffi as of 0.9.4.0

When ghcjs-dom-jsffi-0.9.4.0 is build with the jsffi flag it has GHCJS.DOM.Document in its exported module list.  However, ghcjs-dom-0.9.4.0 has  "GHCJS.DOM.JSFFI.Generated.Document as GHCJS.DOM.Document" in its reexported-module list.  This leads to an ambiguous module error when you try to use it.  I'm not 100% sure this is a bug or if our dependency lists are wrong.
