Test bitcoind wallet behavior during mempool eviction

[t-bast]

When transactions are being evicted from the mempool, we want to make sure that bitcoind keeps the corresponding wallet inputs locked to avoid accidentally double-spending ourselves. We update our unit tests to be closer to common scenarios (chain of unconfirmed splice txs, commit txs replaced by the remote version, anchor tx RBF and htlc txs conflicts).

These tests confirm that:

• if our wallet transaction is directly double-spent by another transactions (either a wallet transaction or an external one), bitcoind automatically frees up inputs when the competing transaction confirms
• if our wallet transaction is invalidated by one of its parents being double-spent, bitcoind keeps wallet inputs locked, and we have to call abandontransaction ourselves to free up utxos
