When duplicating a test don't include "duplicate" word in titles

Since we can now have groups using the same name in one or multiple tests, it would be nice not to have the word "duplicate" added at the end of groups inside a duplicated test.

To reproduce:

1. Duplicate a test

2. Open the duplicated test

3. Notice that all groups, except components, will have the "- duplicate" word at the end

   

This way I could avoid having to remove the "- duplicate" from each group manually.
