MusicXML: Use \skip in lyrics instead of ""

In lyrics, use \skip4 to indicate a note has not syllable attached. So far,
I had "", which caused lilypond to print out several warnings "cannot align
on self: empty element".
As lilypond seems to ignore the time attached to a \skip (but requires some
time indiation), I simply use 4.
