[BUG] last_side appears to not be correctly updated.

[lemon1324]

Blueprint:
Zigbee2MQTT-Aqara-Magic-Cube-T1-Pro-CTP-R01-Xiaomi-Lumi.yaml

Bug Description:
The last_side number helper is created and appears as an MQTT entity, however the value of the number helper is never updated when looking at the entity history. Instead, it is always 'unavailable'

On the other hand, all group 1 actions (those not conditional on last_side) all work perfectly. The template sensor suggested to aid debugging always shows the last action as 'from side 0'.

To Reproduce:
Steps to reproduce the behavior:

1. Import blueprint from https://github.com/SirGoodenough/HA_Blueprints/blob/master/Automations/Zigbee2MQTT-Aqara-Magic-Cube-T1-Pro-CTP-R01-Xiaomi-Lumi.yaml
2. Click on blueprint to make an automation.
3. Add notification action for "side 2 from any side" in group 1, scene mode.
4. Add notification action for "side 5 from side 1" in group 3, scene mode.
5. Side 2 action fires a notification when the cube is flipped; side 5 does not.
6. Viewing trace of the side 5 flip shows that last_side is set to zero, and therefore skips all group 3 actions.

Expected behavior:
The number helper is being created, but I expect it to be updated with the last side each time the cube is flipped.

Screenshots:

History of number helper entity and snapshot of template sensor output.
