Investigate validity of error message when re-deploying on a different CLI version

[RobertLucian]

Description

Trying to re-deploy an API locally with a newer version of the CLI will return the following type of message:

api model was deployed using CLI version 0.17.1 but the current CLI version is 0.18.1; please run `cortex deploy` to redeploy the api or `cortex delete model` to delete the api`�

As reported by @elliotzeitgold.

Expected behavior

Running any of the two suggested commands should work - and not return an error.

Actual behavior

Running any of the two suggested commands in the error message will fail with the same error message.

Part of the error message is indeed contradictory/recursive: please run cortex deploy to redeploy the api or cortex delete model to delete the api. Running cortex deploy or cortex delete would return the same error.
