Camel-pubsub: com.google.api.gax.rpc.AsyncTaskException: Asynchronous task failed with real account

During fixation of https://github.com/apache/camel-quarkus/issues/4062 I noticed regular exceptions shown only with real account (not with emulater):

Suppressed: com.google.api.gax.rpc.AsyncTaskException: Asynchronous task failed		at com.google.api.gax.rpc.ApiExceptions.callAndTranslateApiException(ApiExceptions.java:57)		at com.google.api.gax.rpc.UnaryCallable.call(UnaryCallable.java:112) 

Exception shows that some connections is closed during the acking mechanism. It should be fixed. (To reproduce issue run i.e. run test from CQ with real account GooglePubsubTest#pubsubTopicProduceConsume)
