Make error messages more verbose when debugging

[BalestraPatrick]

When debugging some issues in my code, I noticed that the associated values of the error cases wouldn't be printed to console, making it harder to figure out what went wrong. Merging this improvement changes the debugDescription in order to better diagnose the associated value of type Data for example:

- requestFailure(401, Optional(350 bytes))
+ Request failed with status code 401 and response {
+	"errors": [{
+		"status": "401",
+		"code": "NOT_AUTHORIZED",
+		"title": "Authentication credentials are missing or invalid.",
+		"detail": "Provide a properly configured and signed bearer token, and make sure that it has not expired. Learn more about Generating Tokens for API Requests https://developer.apple.com/go/?id=api-generating-tokens"
+	}]
+ }
