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

64fee48 qt: Assert QMetaObject::invokeMethod result (João Barbosa) f27bd96 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. ACKs for top commit: laanwj: ACK 64fee48 Tree-SHA512: d332e5d7eb2c7be5d3fe90e2e4ff20a67800b9664f6637c122a23647a964f7915703d3f086e2de440f695cfe14de268ff581d0092b7736e911952a4f4d248e25
