This partially reverts the changes from commit020166080cto testnet4_miner_tests.cpp Also, remove some confusing IWYU pragmas. Those were inconsistently added in8c58f63578, but without any rationale why adding them is the correct approach. The correct approach should be done in a proper follow-up, with a clear rationale.
