Test common calibration workflow - enforce unique model names

[ecomodeller]

The default behavior of MIKE FM is to create to store outputs in a folder based on the name of the setup file.
E.g. in this case the file flow.dfsu would be found in the folder oresund_1.m21fm - Result Files

Using the filename (os.path.basename) as the default name for a model result, is thus not likely to be unique.

I don't think modelskill.match should allow multiple models with the same name.

But dealing with a single model it seems completely unnecessary to name a model result.
