Improve logic for searching plugin id in case of module already exists in node_modules

Steps to reproduce
There is the issue with searching plugin id if the module already exists in node_modules.

cordova create sample
cordova platform add android
cordova plugin add cordova-plugin-ms-adal
cordova plugin add ../azure-activedirectory-library-for-cordova (use local folder)

Get error message:
Error: Failed to get absolute path to installed module
This error occurs since folder name in node_modules (cordova-plugin-ms-adal) differs from base name of installation folder (azure-activedirectory-library-for-cordova).
