CLI install of extension reports errors when successful

[sstone1]

When I install the extension using the CLI in a Docker file:

RUN code-server --install-extension /tmp/ibp.vsix

I get the following error message for my VSIX:

Installing extensions...
(node:6) UnhandledPromiseRejectionWarning: Error: Invalid tar header. Maybe the tar is corrupted or it needs to be gunzipped?
    at Object.exports.decode (/src/build/code-server2.preview.11-vsc1.37.0-linux-x86_64-built/out/vs/server/node_modules/tar-stream/headers.js:267:43)

... omitted lots of stuff ...
Extension 'ibp.vsix' was successfully installed.

It works fine, so shouldn't the errors be suppressed?

This might be fixed in GH-857, can you try that out in v2 to see if that persists in there? @sstone1

[sr229]

Confirmed a issue in v2 as well.
