Fix issue with MS Graph batch size, scopes, and exception logging improvements

[nathanthorpe]

• Add default batch size to ms graph fetch messages (fix issue when it is not supplied in the config)
• Add scope parameter when initializing the Graph client with interactive auth to force it to get tokens with that scope.
• Log the trace back information when catching an exception in the main handler
