[FLINK-7287][tests] fix test instabilities in KafkaConsumerTestBase
## What is the purpose of the change
fix test instabilities in KafkaConsumerTestBase
## Brief change log
* Properly ignore the `JobCancellationException` (several tests should have always failed but did not due to not waiting for the job execution thread to finish).
* Always wait for the job execution thread to finish before checking the result of and returning from the test (although this is not strictly necessary for the tests, it may uncover any hidden failures between the cancel command and the actual cancellation but it also allows following tests to work with a clean cluster and no interfering jobs).
## Verifying this change
This change is already covered by existing tests extending `KafkaConsumerTestBase`, such as `Kafka010ITCase`.
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (no)
- The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no)
- The serializers: (no)
- The runtime per-record code paths (performance sensitive): (no)
- Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no)
## Documentation
- Does this pull request introduce a new feature? (no)
- If yes, how is the feature documented? (not applicable)
