Uninstalling an imported module leaves behind an ir.module.module entry
which is entirely useless: it cannot be reinstalled without re-uploading
the module.
A quick solution is provided here by simply cleaning up after the
uninstallation and deleting the ir.module.module records of imported
modules that just got removed.
Another possibility could be to store the uploaded module for good in
an attachment and re-load it from there upon re-installation, but that
would lead to some conflict with Studio, as uninstalling the
studio_customization module usually means you want to get rid of it for
good.
