Rare chance of initial pruning proof building issues

[coderofstuff]

Describe the bug

There is a very rare chance that the initial pruning proof sync is somehow corrupted. Example logs:

To Reproduce

1. Run an initial sync.
2. Most of the times this will not occur, but sometimes it will

Expected behavior
The initial sync and building of pruning proof never fails

Desktop (please complete the following information):

• Kaspad version: 0.13.4

Additional context
This is a MUST FIX bug for adoption of the rust node. The final release must contain the fix for this.

When this is encountered, the only recourse is to delete the datadir and do a resync. Either delete the datadir manually or run kaspad with --reset-db (once)
