Update network checking method in commonUtils
- change method signature: replace 'Account account' parameter by 'boolean isMeteredNetworkAllowed' - Extract code to check meteredNetwork from ContentResolver into a separate method: isMeteredNetworkAllowed(Account account) - Update call to haveNetworkConnection() to fit with new signature. Use "true" for meteredNetwork in Activity, and load settings for ObserverService, SynchronizationService & CreateRemoteFolderWorker.
