Provide access to ExtCodes when the '-f' flag is provided

Currently, ExtCodes are only provided when the 'env' flag is present in
commands. The result is errors occuring when we run commands such as `ks
show default -f components/guestbook-ui.jsonnet`, where the params
ExtVar is needed. This commit fixes that scenario.
