QPersistentModelIndex: fix relational operators not being noexcept

They actually can be, so the implementation need not change. Just add
the noexcept tag (which is BC, it's not part of the name mangling on
any compiler).

Silences a bunch of XFAIL in the test (the test is automatically
picking up the change, no need, and no way, to manually remove the
QEXPECT_FAIL).
