Missing denominated txs and undefined blended txs

[whphhg]

If you are running chainblender or using a wallet that previously had chainblender enabled, you will run into the issue of not having denominated transactions shown in the transactions list and blended transactions having undefined category.

The GUI is using listsinceblock RPC to fetch the transactions which are then looked up further using gettransaction, however if denominated transactions are not returned, the GUI won't know if an output has been used and that a new one is available to be used.

Due to this the address list won't reflect 100% accurate wallet state.
