Description: fix #294866: The direction of beamed notes does not immediately change when the beam is broken
 Resolves: https://musescore.org/en/node/294866.
 .
 When a ChordRest is removed from its beam during layout, we need to
 relayout its old beam. This will cause a recalculation of the stem
 direction, in case it needs to change.
