No referral fee on purpose: it seems like it doesn't really make sense to charge a fee for a migration

Didn't add a prior repay step (which is an action that exists in bundler3), which would allow to repay and withdraw the collateral to deposit on a vault v2. It doesn't seem to make a lot of sense to add it:
- it would be most useful if we integrate a swap mechanism, but it's not planned atm
- it would enable to deposit a collateral into a vault v2, which doesn't seem like a big use case

Not doing slippage check for this withdraw, because withdrawing 1 aTokens give out about 1 underlying:
- token is rebalancing to account for interest
- bad debt can be realized, but it's under Umbrella system which only burns it own aToken (so no "price" repercussion to users)
