Fix search cron worker when indexing is disabled
What does this MR do and why?
It turns out that we don't have a Gitlab::CurrentSettings.elasticsearch_indexing? check in Elastic::BulkCronWorker, which started to cause issues to customers after we enabled the parallel_bulk_cron_worker feature flag by default. The problem is that we schedule a lot of jobs, but Elasticsearch is unreacheable.
