[0Tech]

Description

This patch adds setupUpgradeStoreLoaders(), which handles store upgrades.

How has this been tested?

1. Start v3-Rose chain.
2. Upgrade the chain to v4-Marigold.
3. Access the new module's state.
   • e.g. fnsad q fswap swaps

• Expected results:
  • Without the patch: panics
    • Error: Query failed with (111222): runtime error: invalid memory address or nil pointer dereference: panic
  • With the patch: returns an empty array of swaps.

Checklist:
