cannot find Voice `uniqueContext0' with \context Staff

[Thomas Morley]

Hi,

this came up in the german forum:

\context Staff { b1 }
\addlyrics { foo }

results in not printed lyrics and the warning:

warning: cannot find Voice `uniqueContext0'
\addlyrics
           { foo }

It worked up to 2.18.2 but fails for 2.20.0 and upstream

Changing the code to use
\context Voice or \new Voice or \new Staff
works.

Cheers,
  Harm
