I may have completely misunderstood your question. If so, please excuse me!

As I see it you seem to be trying to start new staffs by using a \break 
command. As far as LilyPond is concerned, however, you only have one staff, and 
it seems to pick the one that comes closest to the start of the music (ie 
'First.') I don't really remember, but it's possible the way Staff.instr was 
handled changed somewhere between 2.6 and 2.8.

Anyway, Lilypond can do this for you automatically, (and the bar numbers will 
be corrct as well, and everything will line up correctly!) Have a look at 
Section 2.8 (More staves) in the manual.

To get you started, here's how I would write your code:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\header{
  title = "Staff.instr ?"
}

musique = \relative {
  c d e f g a b c
}

\relative {
  <<
    \new Staff{
      \set Staff.instrument ="Test"
      \musique
    }
    
    \new Staff {
      \set Staff.instrument ="First"
      \musique
    }
    \new Staff{
      \set Staff.instrument ="Second"
      \musique
    }
    \new Staff{ 
      \set Staff.instrument ="Last"
      \musique
    }
>>
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


Hope this helps!
