Currently, before generating the runner JAR, we are checking if it already exists and deleting it. In case `quarkus.package.add-runner-suffix=false`, the uber-jar file name will (typically) be matching the original JAR name. The issue is that the original JAR is used as a content source for the uber-jar. If the original JAR is deleted before the uber-jar is generated than generated uber-jar won't be usable.
