REVISION SUMMARY
  It doesn't make sense to emit a signal in someone elses layout object
  
  1. only the containment.Layout.preferedSize is ever used
  2. and the only user (panel.qml) is constantly bound anwyay.
  
  I assume it was an attempted workaround for the bug in the panelview
  length cleanup that I did ages ago.

TEST PLAN
  Resized all the things in plasma configure mode.
  No changes.
