_status not reset after FluentLoggerError.MissingTag #94
Description
On FluentLoggerError.MissingTag errors the reconnect handler (https://github.com/fluent/fluent-logger-node/blob/master/lib/sender.js#L453) does not set _status back to established, and does not re-emit the connect event.
Background: I've implemented a bounded event queue that queues if the fluent-logger is not connected, and attempts to flush when the logger reconnects. In cases of event data errors callers cannot be accurately notified of when the logger reconnects either through looking at _status or depending on the connect event.
