Fix non-default-constructible type lists used in TEMPLATE_LIST_TEST_CASE (#1697)

* Fix non-default-constructible type lists used in TEMPLATE_LIST_TEST_CASE

std::tuple is not default constructible when the first type is not
default-constuctible. Therefore it can not be instantiated.
to circumvent this, we have to use std::declval in the unevaluate decltype
context.
