MMR wrong glyph

[Simon Albrecht]

Hello,

in the following snippet the MMR should be displayed with the "rests.M1" 
glyph (vertical bar between two staff lines). But with Timing_translator 
moved to staff level, this works only if the staff is not explicitly 
instantiated (uncomment `\new Staff` to test), else the whole rest 
glyphs are used.

%%%%%%%%%%%%%%%%%%%%
\version "2.19.27"

voiceOne = \relative {
  \time 4/2
  R\breve
}

\score {
  % comment to trigger bug
  \new Staff
  \voiceOne
}

\layout {
  \context {
    \Score
    \remove "Timing_translator"
  }
  \context {
    \Staff
    \consists "Timing_translator"
  }
}
%%%%%%%%%%%%%%%%%%%%

Yours, Simon
