Bernhard Kirchen fe2f82e303 Fix: switch context when handling AC charger MQTT messages
MQTT message callbacks are executed in the MQTT thread context. when
processing topics that control the huawei AC charger, we must avoid
executing methods that are not thread-safe. this change bound the
methods to be called to the respective parameters and executes them
in the TaskScheduler context, such that they no longer need to be
thread-safe.
