When the format of the response received from the outgoing webhook server is invalid (unparsable json, or just wrong format that doesn't translate into a dictionary etc.), a message with the error is sent to the bot owner. We should include the actual payload to make reasonable debugging possible. In notify_bot_owner we have to move the `if response_content` block to append the payload to the message whenever it was specified as an argument to the function. It shouldn't be nested inside `elif status_code` as before.
