    Warn and don't try to balance a transaction with a too-small imbalance.
    
    In a book using trading accounts, if the user sets an account's
    minimum fraction to be smaller than the commodity's and makes use of
    the extra fraction, GnuCash can't create a correct trading split
    because that uses the commodity fraction. Instead of offering to
    balance the transaction, put up an error dialog explaing that the
    transaction can't be balanced.

    Bug 799423 - Crash when creating ETF transaction
    
    Don't keep the old split if it's a trading split. The balance code
    regenerates those, invalidating the pointer.
