huawei_solar: [Bug]: Optimizers missing after HA upgrade

Describe the issue

Hi! After HA upgraded to 2023.7.3, all optimizer information became unavailable. I was with the integration in 1.2.5, so I upgraded to 1.2.6 with no luck. Also uninstalled it and re installed it, and no I don’t even see them. All the optimizers report correctly on FusionSolar.
