StaveModifiers placed at the end of the Stave collide with StaveTies without end notes.

See the collision at the end of the stave in this example:

StaveModifiers placed at the beginning do not exhibit this issue (although the spacing leaves something to be desired):

This is because Stave.setTieEndX() does not accommodate for modifiers.

From src/stave.js:

  getTieStartX() { return this.start_x; }
  getTieEndX() { return this.x + this.width; }

So while getTieStartX() is based on Stave.start_x which changes as modifiers are added, getTieEndX() is just the last horizontal pixel on the stave.

Cool, simple fix then.
