Fix NPE in getMdcCopy of LoggingEventInstrumentation

[ygree]

What Does This Do

Fix NPE in getMdcCopy of LoggingEventInstrumentation

Motivation

Even though the exception is caught, it adds overhead and noise to the telemetry data.

Additional Notes

https://github.com/innoq/log4j/blob/master/src/main/java/org/apache/log4j/spi/LoggingEvent.java#L328-L339

    public void getMDCCopy() {
        if (this.mdcCopyLookupRequired) {
            this.mdcCopyLookupRequired = false;
            Hashtable t = MDC.getContext();
            // If there is no context, it will be null, so this.mdcCopy will also be null.
            if (t != null) {
                this.mdcCopy = (Hashtable)t.clone();
            }
        }
    }
