systemcalc: When AC input set to "Not available" Consumption is doubled

Of course people should not be setting the input to "not available" and then actually use it, so there is no real urgency in this. But maybe there is an easy way to deal better with this.

Example, AC input configured as grid:

Won't fix. When the active input is configured as "Not available", which is not the default, the contribution/load on the input of the Multi is not considered in the calculation and the grid meter's value is copied straight through, making it appear that the value doubles. The answer is to configure it correctly. Closing.
