T1847

Cashtab assumes that a tx with no address object in output is a token tx when parsing tx history. However, the tx could be a normal OP return tx.

This diff flags such a tx as non-token if no token info is available in the API check. Previous behavior failed on the error.

This does not impact utxo parsing, only tx history parsing.

1. DM me for a seed with such a tx in history to test, or send yourself a tx with an OP return output.
2. Observe that the tx is parsed correctly.
