Uploads to testpypi not sustained past first upload

[mdenker]

PyPI and TestPyPI only allow one upload of a specific version -- once in a lifetime. It is possible to delete a released upload -- however, the corresponding version number is then burned. Therefore, although it is super practical to have an upload on testpypi after each merge on the master branch, this will not work past the first release after changing the version number, independent of whether one deletes the PyPI release or not. A solution would be to to make sure that each testpypi release is uploaded to a unique version number, e.g., cobrawap-0.2.1.prnumber

There must be solutions to do this. One should however also note that this requires to delete lots of releases on testpypi once in a while.
