Use QJSValue as method parameter type for the scripting interface
Summary:
If a slot or Q_INVOKABLE has a QVariant as parameter and gets called
from a QJSEngine's script, it receives a QJSValue wrapped as QVariant.
To get a QVariant with the actual value wrapped, calling QJSValue::toVariant
is necessary.
I'm not entirely sure whether this is intentional behaviour of QJSEngine, but
even if it's a bug we'll have to workaround it.
