Description
When sweeping private keys, Electrum does not check coin maturity.
Something along the lines of
if self.utxo_is_coinbase(item) and item['height'] + COINBASE_MATURITY - 1 > self.get_local_height():
continue
should be done. Not sure how best to implement utxo_is_coinbase().
I guess this probably doesn't affect many people.

Research direction
Start from the sweep() implementation and trace how each UTXO is identified, including where coinbase status and local height are available. Confirm how COINBASE_MATURITY should be applied, then verify that immature coinbase outputs are skipped while mature outputs remain sweepable.
