In case of an error the callback is called twice about node-scp2 HOT 2 OPEN

I got the same issue

from node-scp2.

Same issue for me for "download" method !

in case of error, my callback is called twice with differents errors.

the first one :

{ [Error: EISDIR: illegal operation on a directory, open 'C:\\sent\2\REC.xml']
  errno: -4068,
  code: 'EISDIR',
  syscall: 'open',
  path: 'C:\\sent\02\REC.xml' }

the second one :
{ [Error: Permission denied] code: 3, lang: 'en' }

This is what I'm doing :

Scp2.defaults(host);
Scp2.download(source, destination, callback);

from node-scp2.
