I just looked up RemoveEmptyStaves
http://lilypond.org/doc/v2.18/Documentation/notation/modifying-single-staves#hiding-staves
 and I see that 
\override VerticalAxisGroup.remove-first = ##t
is what you need to add to the layout...


\layout {
  \context {
    \Staff \RemoveEmptyStaves
    % To use the setting globally, uncomment the following line:
    % \override VerticalAxisGroup.remove-first = ##t
  }
}
