* Validate that there is JSON data in the string before the string is read via parseJSON()

* Fix handling of 5xx responses from OneDrive when performing a session upload
* Switch to same checks when doing non session upload so that OneDrive exceptions are thrown correctly
* Remove a 'throw e' when curl times out
* Remove a needless 'throw e' when a session upload cannot be found
* Set the upload failed flag when OneDrive errors on session uploads
* Add additional JSON object validation for queries made against OneDrive where a JSON response is expected and where that response is to be used and expected to be valid
* Remove 'else throw e' which causes the application to exit / crash and replace with what the actual error message is from OneDrive
* Make logging of unhandled errors consistent
* Add extra error handling when uploading files for errors received from OneDrive or file system errors
* Flag that the upload failed if there is an exception error raised
* Update logging output for when an error occurs to indicate that the file was skipped
* Log the OneDrive response as log.vlog rather than log.error as it is now being handled correctly
* Throw an exception for 50x errors so that it gets caught correctly
* Clean up logging when exception is generated

* Update scopes as per https://github.com/OneDrive/onedrive-api-docs/issues/1119
* Update that if a 403 error is received, what is the right course of action to take
* Without this throw, uploadLastModifiedTime fails to catch that the 412 error was returned, thus, the retry with a null cTag / eTag is not performed which leads to 'OneDrive response missing required 'id' element' being generated.
* Fix 'Unexpected character '<'. (Line 1:1)' when OneDrive has an exception error
* Validate that the response from OneDrive is a valid JSON object
* Update Sharepoint Document Library handling for .txt & .csv files
