Pipx is unable to recover from "missing internal metadata" scenario #1648
Description
Describe the bug
How to reproduce
Kill a running pipx installation at the wrong time during installation.
Expected behavior
After this scenario is reached the only way to recover is to manually delete the venv associated with the package.
Uninstall will not work on such packages.
However, if pipx can detect such corrupted venvs, it should be able to uninstall them as well.
