Merge #16348: qt: Assert QMetaObject::invokeMethod result

64fee48944 qt: Assert QMetaObject::invokeMethod result (João Barbosa)
f27bd96b5f gui: Fix missing qRegisterMetaType(WalletModel*) (João Barbosa)

Pull request description:

  Invalid/wrong dynamic calls aren't verified by the compiler. This PR asserts those dynamic calls. Once we bump Qt to at least 5.10 these can be refactored to use the `invokeMethod` overload that allows connecting to lambdas or member pointers, which are compile checked.

  For reference, one of the overloaded versions is https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod-5.
