tapis auth tokens refresh fails on expired tokens

[airswing]

Describe the bug
When I open Tapis CLI and try to refresh tokens, I get Failed to load Tapis API client. Run 'tapis auth init [--interactive]' to resolve this.

To Reproduce
Steps to reproduce the behavior:

~$ docker run --rm -it -v ${PWD}:/work -v ${HOME}/.agave:/root/.agave     tacc/tapis-cli:latest bash
🐮 tapis-cli:1.0.0@9af46da3deb3# tapis auth show

+---------------+--------------------------------+
🐮 tapis-cli:1.0.0@9af46da3deb3# tapis auth tokens refresh
Failed to load Tapis API client. Run 'tapis auth init [--interactive]' to resolve this.

Expected behavior
I expect a new access and refresh token pair
