Samuel Gaist 04b180f7f2 Improve std::tuple handling in tests
Currently when doing comparison with std::tuple the fallback toString
method is called which returns a Q_NULLPTR thus not allowing proper
diagnostic of the values that triggered an error. This patch
adds support for std::tuple to improve the tests output readability.

[ChangeLog][QtTest][QCOMPARE] Now outputs contents of std::tuple on
failure.
