Fix a VC crash observed in the local_testnet simulation (#3872)

Browse Source 
It's not quite clear why this condition was triggered in the local
simulation, but it seems a viable scenario after the Keymanager API
is integrated in the validator client.

The user can temporarily remove all validator keys from a running
client before adding another set of keys.
