🔧 Fix storage migration (#316)

## What?
- Fix a bug in the storage migration of pallet funding from 2->3

## Why?
- ProjectStatus was wrongly migrated inside ProjectDetails

## How?
- We added a new status `CalculatingWap` which changed the indices of all enums when encoded, which we forgot to account for

## Testing?
Tested by forking Polkadot and Polimec with chopsticks using `npx @acala-network/chopsticks@latest xcm -r polkadot -p scripts/chopsticks/polimec-testing/polkadot-polimec.yml
`

## Anything Else?
The new chopsticks script replaces the Council and TC with test accounts, which means we can quickly do sudo operations
