Current Behavior:

If I install a package using the --no-save option, it is not removed from node_modules/ upon its uninstallation.

Expected Behavior:

If I install a package using the --no-save option, it should get removed from node_modules/ upon its uninstallation.

NB: this is also how npm 6 behaves.

Steps To Reproduce:

1. Run the following

cd $(mktemp -d)
mkdir node_modules
npm i q --no-save
npm un q --no-save

2. Observe that node_modules/q still exists.

Omitting the --no-save option for the uninstallation command yields the same result. Substituting mkdir node_modules with npm init --yes makes no difference either.

Environment:

• OS: Ubuntu 18.04.5 & 19.10
• Node: 12.19.0 & 15.4.0
• npm: 7.0.15 & 7.1.1
