* Added "option(traversal fail)".
* If there is no index, then QuerySyntaxException is thrown (Sling converts all
kinds of query exceptions to QuerySyntaxException, even if the syntax is fine -
this is slightly confusing, but fixing that would be a backward compatibility
problem).
* This exception is logged at info level, and then converted to
IllegalStateException (a RuntimeException). So if there is no index, the
error.log will show what's going on - just that this is no longer a warning,
just an information.
* The AbstractJobHandlingTest now uses a stable Oak version instead of an
unstable one as before. This is needed because "option(traversal fail)" was
implemented slightly after Oak 1.5.7.
* The Jackrabbit version is updated as well, as that's the version needed by
the newer Oak version
* Adding "jackrabbit-data" is needed as that was added slightly after Oak 1.5.7
(part of modularization).

> The method
> [JobManagerImpl.findJobs|https://github.com/apache/sling-org-apache-sling-event/blob/master/src/main/java/org/apache/sling/event/impl/jobs/JobManagerImpl.java#L373]
> runs a JCR query to find all jobs for a topic.
> It is possible that such a query is running while the repository isn't
> initialized yet, meaning while the index isn't available yet. What is
> happening in this case is that the query is traversing all nodes below that
> path, triggering a warning that the query doesn't use an index. It is
> sometimes happening when a health check is running before the repository is
> initialized (ReplicationQueueHealthCheck and DistributionQueueHealthCheck).
> It doesn't make sense that the query traverses the nodes. It should use an
> index. If the index isn't available yet, it should fail. Therefore, the query
> should use "option(traversal fail)". That would result in an exception that
> can be caught. I will log a related issue to change the health checks to
> process this exception and return HEALTH_CHECK_ERROR for this case.
