FTP: FtpSession Download function misuses async method call

[WMG-VincentW]

The implementation of the Download method of the IFtpSession interface for the standard FtpSession class will not work consistently, because of the misuse of an async call. See the below link, but put simply, the wrapped FTP client has two methods, one synchronous, which is used correctly in the case that the Download method is processing a folder, but in the case of files, the wrapped FTP client's asynchronous method is used, which returns and then does nothing with a Task. This renders this function useless if called on anything other than a directory.

Changing the call on line 443 of FtpSession.cs from:
_ftpClient.DownloadFileAsync(localPath, remotePath, overwrite ? FtpLocalExists.Overwrite : FtpLocalExists.Skip); to _ftpClient.DownloadFile(localPath, remotePath, overwrite ? FtpLocalExists.Overwrite : FtpLocalExists.Skip); should resolve the issue.
