D1619: highlight: eagerly discover plugin lexers while demandimport is off

REVISION SUMMARY
  Since highlight is only relevant for servers, it seems worthwhile to
  just trigger this eagerly, which avoids really weird traceback
  problems caused by demandimport messing with some of the lexer plugins.
