Home Battery Discharge Control not Working with Minimum SoC

[Percy2Live]

Describe the bug

The option "prevent home battery discharge for fast charge" does work well - except if there is a minimum SoC configured for the vehicle. In that case the vehicle will automatically start to charge when plugged in - but the home battery will be used for that.

Expected behaviour: The home battery should not be used in that case, similar to what happens when the fast charge option is selected

Steps to reproduce

1. Activate the option prevent home battery discharge for fast charge
2. Enable a minimum SoC for the vehicle in the arrival tab (e.g. 80%)
3. Plug in the vehicle with a lower SoC (e.g. 50%)

The vehicle will start to charge automatically, but the home battery will be used. When step 2 is skipped and fast charge is selected instead, everything works like expected: The home battery is not used
