class Synced::Strategies::Check

Makes a DRY run of full synchronization. It checks and collects objects which
* are present in the local database, but not in the API. Local AR object is returned - additional objects * are present in the API, but not in the local database, remote object is returned - missing objects * are changed in the API, but not in the local database, ActiveRecord::Model #changes hash is returned - changed objects

If we check model which uses cancel instead of destroy, we skip canceled when searching for additional objects by searching in :visible scope
