Fix: Use correct OpType on Failure in BulkItemResponse

When a bulk request fails on a Delete or Update request, the BulkItemResponse
reports incorrect "index" operation in the response. This PR fixes this
for the case of closed indices as reported in #9821 but also for
other failures and adds tests for the two cases covered.

Closes #9821
