Closes #99

• f8e3fd0 (Martin Günther, 2 years, 3 months ago) test-pyramids: disable debug_view if gui=false

  adding_images_2 had the debug view always enabled, so it failed in docker.

• 24c6ab8 (Martin Günther, 2 years, 3 months ago) test-pyramids: Check all topics

  This test now correctly identifies the errors and fails (which is what we want):
