Calibration error handling not working properly #2743

Steps to reproduce:

1. Create a fitting (any ship, e.g., Astero, calibration = 350)
2. Fit Small Gravity Capacitor Upgrade II (calibration: 0/350 -> 300/350, black calibration text in the top right corner)
3. Fit another Small Gravity Capacitor Upgrade II (calibration: 300/350 -> 600/350, black calibration text in the top right corner)
4. Toggle one of the rigs from online to offline (the icon in front of the element changes from a yellow circle to a red cross)
5. Calibration text in the top right corner changes to 300/350 and is red (this is incorrect).
6. Toggle the offlined rig to online, and the calibration text changes to black again.

The expected behavior is the same as with the drones text right next to it: If you have 5/5 drones active and activate another flight, the drone text says 10/5 while also being (correctly) red.

Thanks and kind regards,
