Synthesis View: Crash when opening without an imported project

Steps to reproduce

  • Switch to DSE perspective
  • Open synthesis view
  • Select synthesis type (e.g. Deployment)
  • Observe below NPE

Hint:

  • Probably, the synthesis, constrants und visualization button should be disabled as long as no project has been imported.
  • However, also the synthesis view should be made more robust and should prevent this NPE (the view might be restored without using the “Synthesis” button after closing and starting AF3)
