inconsistency between 010_install_plugins.js hook and ionic state reset way to read package.json plugins

[Freundschaft]

The 010_install_plugins.js hooks added by using ionic hooks add uses a different method of adding plugins, allowing it only to read strings for cordova plugins add (https://github.com/driftyco/ionic-cli/blob/master/lib/hooks/after_platform_add/010_install_plugins.js#L26).
Something like

{
      "locator": "https://github.com/gfnork/Calendar-PhoneGap-Plugin.git",
      "id": "cordova-plugin-calendar"
}

will fail to be added by this hook.

This is largely inconsistent with the behavior of ionic state reset which uses a more sophisticated way to read the package.json and generate the cordova plugins add command. (https://github.com/driftyco/ionic-app-lib/blob/master/lib/state.js#L511)

I know the ionic state reset command is planned for deprecation, but to be honest, I think this could be fixed fast and painless until the ionic state reset command is removed

I just added a PR for the changes by simply Copy pasting from ionic app lib, can this be merged?

Hello! Thanks for opening an issue with us. We are currently in the process of deprecating the ionic state commands in favor of doing it the cordova way. https://cordova.apache.org/docs/en/latest/platform_plugin_versioning_ref/index.html You can keep up with the status of this on #904 . Thanks for using Ionic!
