[Bug]: Splitting a transaction that is a transfer to another account off budget does not match up

### Verified issue does not already exist?

- [x] I have searched and found no existing issue

### What happened?

I split a transaction that is a transfer to an off budget account.

In the off budget account, it does not allow you to link to the transfer, but ends up adding 2 transactions.

These 2 transactions then cannot be marked as transfer, so there is the $3000 transaction and the split transactions showing up separately causing an additional $3000 to show up in the off budget ledger.

### How can we reproduce the issue?

I would expect that the split would exist on both accounts and not show up as 2 new transactions that is not markable as transfers.
