Merge bitcoin/bitcoin#27806: fuzz: Fix mini_miner_selection running out of coin
76c5ea703e77d580b6962e60398f4988cbd9b58b fuzz: Fix mini_miner_selection running out of coin (Murch)
Pull request description:
Fixes a bug in the mini_miner_selection fuzz test found by fuzzing: It was possible for the mini_miner_selection fuzz test to generated transactions that created fewer new outputs than the two inputs they each spent. If the fuzz seed did so consistently, eventually it would cause a `pop_front()` on an empty available_coins which resulted in undefined behavior.
Fixed per belt-suspender approach:
- assert that available_coins is not empty before generating tx
- generate at least two coins per new tx
- allow building tx with a single input if only one coin is available
