OMEdit does not rename file and does not update the package.order file when model is renamed

[Andrea Bartolini]

If you create a package with the option to save models in single files and then you rename a model the name inside the model file is updated but not the file name.
Moreover, also the content of package.order file is left unchanged.

The expected behavior is that also the file is renamed, a copy of the original file is kept on disk, renamed as .bak, and the package.order file is updated with the new model name.

In order to reproduce the problem you can open the attached zip, extract the model and execute the following steps:

• open Test package in OMEdit
• open M1 model inside the package
• from the text view, rename the model as you want (e.g. M11)
• save the model, the text inside the file M1.mo is updated but the name of the file M1.mo doesen't change and the content of the package.order file is left unchanged
• open the P1 package inside the Test package
• redo the same for the model M2, the same problem will happen
• if now you unload and reload the Test package, you get an error (as expected)
