Merge #16348: qt: Assert QMetaObject::invokeMethod result
64fee489448c62319e77941c30152084695b5a5d qt: Assert QMetaObject::invokeMethod result (João Barbosa) f27bd96b5fdc2921d93c44bbf422bff0e979c4de 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.
