title: Removing a package from composer with --no-update
body: <p>I'm trying to remove a package from my application and I've run <code>composer remove --no-update package/name</code>, now all this does is remove the entry in <code>composer.json</code> but when I run <code>composer show -i</code>, I see the package is still installed, is there anyway to completely remove a package without running update?</p>
