FTP error while handling multiple directories

[GochoMugo]

There's seems to be a bug with the FTP module, when handling multiple directories.

 >>> DirDone with Error: inner :: Error: 530 You aren't logged in
 >>> DirDone: .

Refer to issue sergi/jsftp#115

It happens that the feature in #2 may help work around this bug (as we continue to look into the bug in the underlying FTP library).
