🐛[jsonStringify] do not crash on serialization error

fixes #236

If I understand correctly, when doing DD_LOGS.logger.info('hello', window) the logs intake will receive "<error: unable to serialize object>" instead of an object. I think it would be better to not send anything in this case.

Yes

IMLO, swallowing the error could be quite frustrating for the user. With this approach, the user see that one of his log as been triggered and can try to understand which one is the culprit.

All right I didn't know the logs intake could take a simple string as input.
