Xiaomi: implement setAutoReconnect on XiaomiSupport

The DeviceCommunicationService calls `#setAutoReconnect` on new device
supports before it calls the connect method. Since this method did not
get relayed to the connection-specific support classes, Xiaomi devices
using a BLE connection did not automatically reconnect because the
`mAutoReconnect` field in `AbstractBTLEDeviceSupport` never got set.
