fix: prevent crash loop on pruned state — patch getExtrinsicSuccess and events.toArray

Browse Source 
When SubQuery restarts and hits pruned blocks, events are empty (from patch 4).
This caused two downstream crashes:
- getExtrinsicSuccess(undefined) → TypeError on findIndex
- wrapBlock with events.toArray() → TypeError on undefined

Patches 5-6 handle undefined events gracefully.
