tdeioslave/sftp: pass correct username to openPassDlg()
We should always pass to the openPassDlg() exactly the same username otherwise it may result in incorrect caching of passwords especially in case if the username is changed by the user. Also don't allow username change in case it was passed to setHost() (i.e. it was specified in the URL like e.g. sftp://username@host/). In such a case after changing it'd be impossible to properly cache it. Signed-off-by: Alexander Golubev <fatzer2@gmail.com>
