This PR adds missing test coverage for the bumpfee RPC error "Transaction has descendants in the mempool",
bitcoin/src/wallet/feebumper.cpp
Lines 29 to 32 in 6419bdf
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.
