The listunspent RPC command currently mixes currency outputs and name outputs in the current wallet, which is not good (even though the name outputs are marked as spendable: false). Worse, even expired names (whose output no longer even exists in the UTXO set) are present in the output.

What we should fix:

• Expired names should in no case be present in the output.
• For unexpired names, we should either also not include them at all (as they can be queried with name_list), or at least clearly mark them with a new field in the JSON result. E. g., name: "some_name" for name outputs, and name: null / missing for currency outputs.
