Descriptor wallets are already created by default since v23.0, but
since the recent legacy wallet removal this parameter *must* be True
(see commit 9f04e02ffaee0fe64027dc56c7bea3885254321a), i.e. still
passing it wouldn't contain any information for test readers
anymore. So simply drop them in the functional tests in order to
reduce code bloat.
