\RemoveEmptyStaffContext has been replaced by \Staff \RemoveEmptyStave
in version 2.13.something.

And IIRC default settings for  PianoStaff  is to remove either both
staves if both are "empty", either none if only one is empty (and the
other one contains notes).

If you want to remove the staves independently (if empty), try

\layout {
 \context {
   \Staff
   \RemoveEmptyStaves
 }
 \context {
   \PianoStaff
   \remove "Keep_alive_together_engraver"
 }
}


Cheers,
Xavier

PS : Current stable version is 2.14.2, please consider updating
(instead of using an old development version).
