b128b566725a5037fdaea99940d1b9de5553d198 test: add logging for mining_getblocktemplate_longpoll.py (Sebastian Falbesoner) 8ee3536b2b77aeb3a48df5b34effbc7345ef34d8 test: remove unused helpers random_transaction(), make_change() and gather_inputs() (Sebastian Falbesoner) fddce7e199308d96e366d700dca982ef088ba98b test: use MiniWallet for mining_getblocktemplate_longpoll.py (Sebastian Falbesoner) Pull request description: This PR enables one more of the non-wallet functional tests (mining_getblocktemplate_longpoll.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078. Also adds missing log messages for the subtests. This was the only functional test that used the `random_transaction` helper in `test_framework/util.py`, hence it is removed, together with other helpers (`make_change` and `gather_inputs`) that were again only used by `random_transaction`.
