ly:expect-warning not working

[Knute Snortum]

I haven't been able to get the ly:expect-warning function working properly.  Here is a MWE:

%%% Start

\version "2.19.83"
\include "english.ly"

#(ly:expect-warning "omitting tuplet bracket")

{
  \clef bass
  \tuplet 3/2 4 {
    <<
      { g4 s8 gf4 s8 f4 s8 s4. }
      \\
      { g8 ef' bf gf ef' bf f ef' a, bf, df' bf }
    >> |
  }
}

%%% End

This will still emit warnings for me.  I'm on Ubuntu 19.04 if that matters.
