…5772) We seem to have a couple of checks to make sure we delete the data stream when the last index reaches the delete step however, these checks seem a bit contradictory. Namely, the first check makes use if `Index` equality (UUID included) and the second just checks the index name. So if a data stream with just one index (the write index) is restored from snapshot (different UUID) we would've failed the first index equality check and go through the second check `dataStream.getWriteIndex().getName().equals(indexName)` and fail the delete step (in a non-retryable way :( ) because we don't want to delete the write index of a data stream (but we really do if the data stream has only one index) This PR makes 2 changes: 1. use the index name equality everywhere in the step (we already looked up the index abstraction and the parent data stream, so we know for sure the managed index is part of the data stream) 2. do not throw exception when we got here via a write index that is NOT the last index in the data stream but report the exception so we keep retrying this step (i.e. this enables our users to simply execute a manual rollover and the index is deleted by ILM eventually on retry)
