v2.3: Recalculates the accounts lt hash when creating minimized snapshots (backport of #6843)

[mergify]

Problem

If a minimized snapshot is created, and the accounts lt hash feature is enabled, the new snapshot will fail to load because the initial startup accounts verification will fail.

This is because the accounts lt hash in the snapshot will be the pre-minimized value, based on the pre-minimized account state. If the account state is changed—as it is when creating a minimized snapshot—then then accounts lt hash must be recalculated.

Summary of Changes

Recalculate the accounts lt hash when creating a minimized snapshot.

Justification to Backport

The bug exists in all versions that support both creating minimized snapshots and the accounts lt hash feature, which includes v2.3.
