fac95398366f644911b58f1605e6bc37fb76782d qa: Run all tests even if wallet is not compiled (MarcoFalke) faa669cbcd1fc799517b523b0f850e01b11bf40a qa: Premine to deterministic address with -disablewallet (MarcoFalke) Pull request description: Currently the test_runner would exit if the wallet was not compiled into the Bitcoin Core executable. However, a lot of the tests run without the wallet just fine and there is no need to globally require the wallet to run the tests.

"""Test the abandontransaction RPC.
|
|
|
|
The abandontransaction RPC marks a transaction and all its in-wallet
|
|
descendants as abandoned which allows their inputs to be respent. It can be
|
|
used to replace "stuck" or evicted transactions. It only works on transactions
|
|
which are not included in a block and are not currently in the mempool. It has
|
|
no effect on transactions which are already abandoned.
