Eike Hein 2c6dacea38 Fix the infamous 'dialogs show up on the Task Manager' bug once more.
- Initially set state (and type, and flags) in response to PlatformSurfaceCreated.
  We know reliably this will run before the window is mapped.

- Drop the comment about removing setState() form showEvent handler, as
  we need it to avoid state loss in this scenario:
  <mgraesslin> the window gets mapped first time: everything is fine
  <mgraesslin> window gets unmapped: kwin removes the state as per spec
  <mgraesslin> qt gets change event and removes the states it doesn't care about
  <mgraesslin> qt maps window again and sets states
  <mgraesslin> we lost the state
  <mgraesslin> which means we need to set the state again from our side before(!) Qt sets it
  <mgraesslin> and before Qt maps the window
