When importing a CS-Import file that contains ConformanceGroups, Libraries, Settings or Profiles that are already existent in the corresponding models, the following happens:

• Profiles are added/replaced in the model, but the same category is shown multiple times in the view (fixed after reloading the project)
• ConformanceGroups are replaced as a whole in the model but the old CG with the same name is still visible in the view (also fixed after reloading the project)
• Settings are shown multiple times, but remain unchanged/disappear after restarting
• Libraries are shown and actually created multiple times in the library model/view

After fixing this, everything should be merged/updated into the existing structures and properly updated in the view without the need to reload the project.

Additionally when importing Conformance Groups, the user should receive a prompt to merge Test Cases/Conformance Units into an existing Conformance Group or replace it as a whole, as well as prompts to keep or update existing libraries.
