What happened?

When cloning a Project with Project Tags defined, you are presented with an error and unable to clone.

Reproduction

1. Created a Tag Set that is scoped to project

3. Save the Project
4. In the kebab menu, next to the save button, click on clone
5. Type in a new Project name
6. Click Clone
7. you will be presented with an error

Error and Stacktrace

The instance of entity type 'ProjectTag' cannot be tracked because another instance with the same key value for {'ProjectId', 'TagId'} is already being tracked. When replacing owned entities, modify the properties without changing the instance or detach the previous owned entity entry first. Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the conflicting key values.
