Merge #17947: test: add unit test for non-standard txs with too large tx size
4537ba5f21ad8afb705325cd8e15dd43877eb28f test: add unit test for non-standard txs with too large tx size (Sebastian Falbesoner) Pull request description: Approaches another missing unit test of issue #17394: Checks that the function `IsStandardTx()` returns rejection reason `"tx-size"` if the transaction weight is larger than `MAX_STANDARD_TX_WEIGHT` (=400000 vbytes).
