Just add an equivalent grace note spacer in the other voices, as shown in the 
NR 
(http://lilypond.org/doc/v2.19/Documentation/notation/special-rhythmic-concerns#grace-notes,
 under "Known Issues and Warnings"):

\version "2.19.83"

vocal = \relative c'' {
        \clef treble
        \key aes \major
        \grace s16      % <-- Here
        R2.
}

upper = \relative c'' {
        \clef treble
        \key aes \major
        \grace s16      % <-- and here
        c4 ees4 g4
}

lower = \relative c' {
        \clef bass
        \key aes \major
        \time 3/4
        \grace b,16( <f c'>2.) |
}

\score {
  <<
    \new Voice = "mel" { \vocal }
    \new PianoStaff <<
      \new Staff = "upper" \upper
      \new Staff = "lower" \lower
    >>
  >>
  \layout {}
}
