Restricted Application added a project: Plasma on Wayland.

REVISION SUMMARY
  The QtExtendedSurfaceInterface might be unbound and thus the resource
  might be null when calling into close. Thus we need to do a nullptr
  check.
  
  Hit a crash there.

TEST PLAN
  Unfortunately no test case as we don't have a client side
  implementation for this.
