Fungible and fungibles adapters should allow account death like burns and mints

[franciscoaguirre]

The fungible and fungibles adapters set the preservation of the burn operation to Expendable: here and here.
This allows accounts to transfer all their funds (and getting reaped because of it) out of their account.
However, this only works if they're using the WithdrawAsset and DepositAsset instructions, which correspond to burn_from and mint_into.
If TransferAsset is used, as is the case with limited_reserve_assets_transfer, then the transfer function will be called with Preserve.

This distinction is arbitrary and we should change the way TransferAsset is handled to also allow transferring all the funds of an account. It results in confusing errors for users.
If needed, we could add a Hint for changing the default of ALL operations from Expendable to Preserve.
