Allow brand new stake interest transactions into the QT transaction table

This change will allow brand new stake interest transactions from user's
just generated POS blocks to get entered into the QT transaction list.
If the new POS block gets orphaned, the transaction will get an undefined
status. But if the QT clint is closed and re-opened, the orphaned stake
transaction will then dissapear.
