Abruptly stopping node while project reindex is in progress causes inability to reindex Jira

Issue Summary

Abruptly stopping node while project reindex is in progress causes inability to reindex Jira.
This problem is a more specific version of JRASERVER-47045

Steps to Reproduce

1. Run a project reindex on node 1
2. Abruptly terminate Jira process on node 1
3. On node 2, go to Jira settings > System > Indexing page

Expected Results

Upon visiting Indexing page on node 2, reindexing operations are available.

Actual Results

Re-indexing operations are not available. The following message is displayed:

The 'Lock Jira and rebuild index' option is unavailable while other indexing operations are in progress. See the Jira log for more details.

Workaround

• If on Jira 8.5.4, 8.8.0 or higher, the stale task will get automatically removed within 30 minutes, that will self-resolve the problem (see - JRASERVER-66204)
• Otherwise, restart the node that initiated the task, so the stale task gets cleared.
  • if it's hard to understand which node initiated the task, you can do a rolling restart.
