Add logging as to why resume upload failed (Issue #468)

[abraunegg]

• Log 'why' the resume upload failed
• Remove the 'resume_upload' as it is invalid & contains bad data

To test that is is working, the following can be added before line 87:

					writeln("making fake response");
					
					response = [
							"id": JSONValue("asdfasdf"),
							"cTag": JSONValue("asdfasdf")
							];
					
					// do we have a valid response from OneDrive?
