Config auto-init behaves strangely with empty config

[t1m0thyj]

Steps to Reproduce

1. Create an empty config file: zowe config init --no-prompt
2. Run auto-init specifying host and port: zowe config auto-init --host example.com --port 7554
3. Enter username and password when prompted

Actual Behavior

• User, password, and token value are all stored by the credential manager. User and password get stored because autoStore is true.
• The hostname specified on the command line is used to obtain the token but does not get stored in the config file.

Expected Behavior

• User and password should not be stored because they would take precedence over the token value. This could be fixed by passing autoStore: false to the prompting method like we do in BaseAuthHandler.
• The hostname specified on the command line should replace the empty hostname in the config file.
