Merge bitcoin/bitcoin#25955: test: use `sendall` when emptying wallet

28ea4c7039710541e70ec01abefc3eb8268e06f5 test: simplify splitment with `sendall` in wallet_basic (brunoerg)
923d24583d826f4c6ecad30b185e0e043ea11dfc test: use `sendall` when emptying wallet (brunoerg)

Pull request description:

  In some tests they have used `sendtoaddress` in order to empty a wallet. With the addition of `sendall`, it makes sense to use it for that.
