Pulumi refresh fails when plugin version is not found

[dbilleci-lightstream]

Posting per request of @swgillespie - this seems to be related to #2608 but he asked that I post a new issue because there can probably be better handling for "refresh".

Here's the gist:

• We use Pulumi in our pipelines, and it's self-contained in a docker container.
• Generally only the latest versions of Pulumi and the Azure and AWS plugins are installed in the container
• We have a "nonstandard" package.json configuration as described in package.json not found by CLI if above local folder #2608 basically at the top level of our pulumi projects (/data/pulumi/package.json in the below example) we have one package.json that has the dependencies for all stacks
• In our pipelines, we currently run a "refresh" step before the "destroy" step when we go to teardown to correct drift
• With the above context, the refresh fails

Here is some output showing the issue:

deploy@3085431aa1b4:/data$ pulumi plugin ls

Let me know if you need any more information.
Thanks!
