384273260a6ccbcf79dade0830011f528e5a1581 test: Add testing of value_ret for SelectCoinsBnB (Ben Woosley)

Pull request description:

Fix that the early bailout optimization tests did not test the intended
selection because their utxo pool was polluted by the make_hard_case test
preceding. Note the code was tested, just not with the constructed case.
