cordova prepare doesn't install the correct plugin versions

according to the documentation at https://cordova.apache.org/docs/en/latest/platform_plugin_versioning_ref/#plugin-versioning plugins should install the version from either config.xml or package.json. However, the latest version is always installed instead.

How to reproduce:

cordova create test
cd test
cordova platform add android
cordova plugin add cordova-plugin-splashscreen@4.0.0

Note how

cordova plugin ls

Shows that version 4.0.0 is installed. Also config.xml and package.json both indicate that 4.0.0 is installed.

Now delete the 'platforms' and 'plugins' folder and run

cordova prepare

Note how config.xml and package.json still indicate that 4.0.0 installed, however when running

cordova plugin ls

it shows

cordova-plugin-splashscreen 4.1.0 "Splashscreen"
cordova-plugin-whitelist 1.3.3 "Whitelist"

 
perhaps I'm missing something, though my understanding is that when `cordova prepare` is run, all plugins and platforms will be installed with their version as listed in package.json and config.xml.

cordova plugin rm cordova-plugin-splashscreen
cordova plugin add cordova-plugin-splashscreen@4.0.0

Installs the correct version again, but that kind of defeats the purpose of cordova prepare.
