 Issue body: It seems we can not find the remote files.

 Comment 0: I had this issue when I first started with remote-ftp. for me it was because a slash is required at the end of the remote path in my **.ftpconfig**
I changed from:

    "remote": "/home/user1/domains/domain.com/private_html",

To 

    "remote": "/home/user1/domains/domain.com/private_html/",

And it worked!

Thanks, but my question was how to find files in the Remote when I select "Find<Find File" from the Atom top menu.
The local files only could be found.
