keystore list dies if no keystore setup

[kanej]

On a new install running npx hardhat keystore list throws a type exception:

hardhat keystore list       
An unexpected error occurred:

I can confirm, that this was because the I had an existing keystore.

On deleting the keystore file I am able to list and set my local keystore.

Note: on mac the keystore file is stored at: /Users/kanej/Library/Preferences/hardhat-nodejs/keystore.json

In HH2 the file is called vars.json, so we won't clash with keystore.json
