Once client gets 401/403 from the server, check if remote wipe was requested.

- When the the users logs because of 401 or 403 errors, it checks if the
server requested the remote wipe. If yes, locally deletes account and folders
connected to the account and notify the server. If no, proceeds to ask the
user to login again.
- The app password is restored in the keychain.
- WIP: The change also includes a test class for RemoteWipe.
