nlst should return relative path

[sebfie]

Hello,

I have an issue with this gem :

• In production, nlst command return an array like ["GDV_1_STOCK_20171028_020152_049.csv"]
• In tests with your fake_ftp, it returns absolute path like : ["/input/scm/stock_items/pending/GDV_1_STOCK_20171028_020152_049.csv"]

Did you notice that?

Thx for this gem anyway !
