Do not add spaces to single letter sub-syllables in elisions

Elision sub-syllables that contain a single letter are having a non-breaking spaced added to them (see issue https://github.com/humdrum-tools/verovio-humdrum-viewer/issues/853).

The spaces in the sub-syllables should be supporessed when they are part of an elision.
