Adapt wallet UTXO selection to dust patch

[michaelsutton]

Applies a fix to the wallet UTXO selection algorithm: if the created transaction has a change output (and thus 2 outputs overall), try having at least 2 inputs as well (in order to not be slowed down by dust patch).

Note that the auto-compound case does not require any adjustments. If the last tx in the compound op has a single input, there wouldn't be a need for the last level in the compound tree
