Poetry remove doesn't remove package

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: GNU/Linux 4.18.7-1-default, openSUSE Tumbleweed
