Merge bitcoin/bitcoin#23281: test: check that bumpfee RPC fails for txs with descendants in mempool

4ac8c89ad9 test: check that bumpfee RPC fails for txs with descendants in mempool (Sebastian Falbesoner)

Pull request description:

  This PR adds missing test coverage for the bumpfee RPC error _"Transaction has descendants in the mempool"_,

  6419bdfeb1/src/wallet/feebumper.cpp (L29-L32)

  which is thrown if the bumped tx has descendants in the mempool and is _not_ connected to the bitcoin wallet (for those, the error "Transaction has descendants in the Wallet" is thrown a few lines above). To achieve that, the test framework's MiniWallet is used.
