Interceptor should not block axon query

[janvonneree]

Maybe a really rare case but the axon open admin should not block axon functionalities.

`Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.util.ConcurrentModificationException] with root cause

java.util.ConcurrentModificationException: null at java.base/java.util.HashMap.computeIfAbsent(HashMap.java:1221) at com.insidion.axon.openadmin.insights.InsightRegistrationService.reportOriginMessage(InsightRegistrationService.kt:16) at com.insidion.axon.openadmin.insights.InsightDispatchInterceptor.originDispatchInterceptor$lambda-2(InsightDispatchInterceptor.kt:49) at org.axonframework.messaging.MessageDispatchInterceptor.handle(MessageDispatchInterceptor.java:43) at org.axonframework.axonserver.connector.DispatchInterceptors.intercept(DispatchInterceptors.java:45) at org.axonframework.axonserver.connector.query.AxonServerQueryBus.query(AxonServerQueryBus.java:258) at org.axonframework.queryhandling.DefaultQueryGateway.query(DefaultQueryGateway.java:84) at org.axonframework.queryhandling.QueryGateway.query(QueryGateway.java:91)`

@CodeDrivenMitch could you already have a look at this? It seems to happen from time to time and causes Axon queries to fail. Any hint would be appreciated if and when this could be fixed.

@CodeDrivenMitch I made a small change, that should avoid concurrency issues in the InsightRegistrationService. It would be nice if you could merge and release it.

@CodeDrivenMitch any news? Is this library dead?
