This exercises the bug inside CoinsResult::Erase that ends up on (1) a wallet crash or (2) a created and broadcasted tx that contains a reduced recipient's amount. This is covered by making the wallet selects the preset inputs twice during the coin selection process. Making the wallet think that the selection process result covers the entire tx target when it does not. It's actually creating a tx that sends more coins than what inputs are covering for. Which, combined with the SFFO option, makes the wallet incorrectly reduce the recipient's amount by the difference between the original target and the wrongly counted inputs. Which means, a created and relayed tx sending less coins to the destination than what the user inputted. Github-Pull: #26560 Rebased-From: cf793846978a8783c23b66ba6b4f3f30e83ff3eb
