Support object field access for ParameterizedTest's name

[Phlegethonyarre]

@ParameterizedTest(name = "...") provides feature to get it's argument value into it's name by using '{0}'.

The common use is that i want to use an Object within an argument (for example User).
In this case i have to go with providing another string argument into test source, that looks like
@ParameterizedTest(name = "I am testing user with name {0}")
void testUser(String userName, User user) {
...
}

But what people need is provide only User argument and access needed field through name (user.getName() or user.name):
@ParameterizedTest(name = "I am testing user with name user.name")
void testUser(User user) {
...
}

Please allow us to do this <3
