evcc: go-e: session energy gets stuck when charging is paused over night in PV mode

Describe the bug

I observed multiple times that the charged counter that displays how many kWh have been charged gets stuck when the charging is paused for some hours or overnight.

For example, I started loading my vehicle yesterday in PV mode. Throughout the day, 9.3 kWh have been sent to the car’s battery. I did not stop the charging process overnight, but just let evcc manage it. As there was no surplus, the loading stopped at some time yesterday afternoon. Today around noon, when some surplus was available, the charging resumed. Even though the car state of charge display shows progress, the “charged” counter gets stuck at yesterdays 9.3 kWh.

The screenshot below shows inconsistent numbers:

Steps to reproduce

1. Start Loading in PV mode
2. After sunset, check the charged counter
3. Wait until there is some surplus available the next day
4. The charge counter will not be updated
