Project can not be updated because the short name is wrong (a number)

I have promoted the sandbox project to a full project but I was mistaken and left the short name with the default number (I thought that the title of the module was enough). Now I can edit the project, but it shows an error every time I try to save it. The error says:
Short name must follow PHP naming convention.
because the short name is a number.

Is there any way of changing the short name from the number to: webform_calculation_components so I can update it?

The project has been approved and users have asked me how can they find it and download it. I also need to make some fixes.

Now there is no way of changing the status to obsolete or unsupport etc., (because it throws the error) and start it over with another project.

Thanks in advance, cheers!
