Error with duplicate objective names

[ellepin]

Describe the bug

When there are multiple target values, the function of the output tab does not work if there are names of the same objective name.
The same does not work if there are two empty objective names.

To Reproduce

1.Open sample.gh.
2. Delete and empty the names of objective "v0" and "v1".
3. Run optimization in Tunny.
4. From the output tab of Tunny, click on "Pareto solutions"
5. The process bar stops in the middle of the process and nothing happens after waiting.

When started in debug mode, "System.ArgumentException" is generated and the program is terminated. Error occurs when the "objectives" variable in dictionary format tries to have the same key.

Expected behavior

Environment

Thanks for the report. I have checked about the bug and will fix it.
If an incorrect objective nickname is entered, an error will be generated.
