prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  project list does not show text if there are no matching projects
  It should show something like "No projects could be found". Note that the text should work for two cases: "there are no projects" and "there are no projects matching the filters".
  
  --- END ISSUE ---
