[#10407] Found some issue , when i using kafka consume, with kafka-coroutine context

[gipyeong-lee]

resolves #10407

Trace trace = traceContext.currentTraceObject();
        if (trace == null) {
            return;
        }

This codes always cut tracing. there is no trace object.
make beforeTraceId in agent context, and load it for continue tracing .
just feedback to me.
