fa6c62f34b50818102ad58f2ffd152189f54d973 test: Replace log with assert_equal in wallet_abandonconflict (MarcoFalke)
Pull request description:
This will make the test fail as soon as the bug is fixed, forcing it to
be updated. Otherwise, the bug might be fixed (or made worse)
accidentally, leaving the test in an inconsistent state.

"""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.
