Poetry self uninstall failing on Windows

Issue

When I run "poetry self uinstall" on windows I get the following error message:

Reproduce the Windows self-uninstall failure and start with poetry/console/application.py and poetry/plugins/plugin_manager.py, following the traceback through the poetry_plugin_export imports. Check how the missing poetry.core.toml module affects command startup and error rendering; done means the self-uninstall command completes on Windows without this traceback.
