Removing the validator key and then sending SIGHUP to the neard process does not appear to stop it validating

[Pete-LunaNova]

Describe the bug
Removing the validator key from the active validator node and then sending a SIGHUP signal to the process produces log output showing the config file being reloaded and that no validator key is found. However, the node appears to continue as a validator with the text "Validator |" on every stats line that lists the number of validators.

To Reproduce
Remove the validator key file on a running active validator node and send a SIGHUP signal to the neard process

Expected behavior
I would expect the node to stop validating when it has detected that no validator key is present after it receives a SIGHUP signal and that there should not be the text "Validator |" on every stats line in the logs.
