Function fix_optional_account_metas

pub fn fix_optional_account_metas(
    accounts: impl ToAccountMetas,
    original: &Pubkey,
    current: &Pubkey,
) -> Vec<AccountMeta>

Change the pubkey of any readonly, non-signer [AccountMeta] with the pubkey equal to the original program id to the new one.

This is a workaround since Anchor will automatically set optional accounts to the Program ID of the program that defines them when they are Nones, if we use the same program but with different Program IDs, the optional accounts will be set to the wrong addresses.

Warning

Use this function only if you fully understand the implications.
