[cdc_rsync] Fails to overwrite directory with a file

[ljusten]

Repro:

• Non-empty folder exists in /path/to/foo
• cdc_rsync.exe foo user@host:/path/to/ (where foo is a file)

This will report this error:

Error: Server returned error: remove() failed: Directory not empty.; Failed to remove folder '/path/to/test' before creating file '/mnt/developer/test'; Failed to copy files

Also, this error is not properly displayed in Visual Studio. VS just reports that sync failed with exit status 1.
