Missing to update host’s hight and timestamp upon a successful upgrade client

[Farhad-Shabani]

Summary

When performing a client upgrade, the pertinent incoming message undergoes processing within the update_state_on_upgrade method. In this process, the handler only updates the store with the new client and consensus states. However, it is essential to note that the associated metadata, which records the timestamp and height of hosts where the upgrade was processed, also requires updating.

To ensure this, it is imperative to call both the store_update_time and store_update_height methods just after storing the upgraded client and consensus states.
