TEMPLATE_TEST_CASE does not support template templates

[ghost]

Description

TEMPLATE_TEST_CASE only supports substitution of simple types, and not template templates.

Steps to reproduce

template <template <typename> typename T>
struct Foo { };

TEMPLATE_TEST_CASE("instantiate a template template with int", "", Foo) {
     using T = TestType<int>;  // ... or something
}

@porpoises in your example you probably wanted to do

template<typename T>
struct Foo {};

in linked PR #1457 i added support for this kind of types. For this kind of tests you will have to use
TEMPLATE_TEMPLATE_TEST_CASE.
