Add nuke migration for loans & interest-accrual

[lemunozm]

Description

Fixes #1461

Changes and Descriptions

• Nuke migration for pallet-loans
  • Tested in altair and centrifuge, and currently, there is nothing there. Should we then add the migration? I think it makes sense to remove anything anyone can add these days there until the next release.
• Nuke migration for interest-accrual
  • I removed the old StorageVersion storage in order to use the new one.
  • Found some rates that we can delete.
