QQmlListAccessor: Store integer if m_type is Integer

When we pass a QVariant to QQmlListAccessor::setList which contains
something convertible to a number, we set the type to Integer. Later, we
simply return whatever is stored internally in the variant, and cast it
into an int. That goes horribly wrong if the variant actually contains a
floating point number.
To fix this, we now store the actual integer in the variant after the
checks are done.
