Fixing cdsdashboard conda environments being shown

[costrouc]

This is a short term fix for conda-store environments being shown in
cdsdashboards. Longer term we will need to consult the conda-store
rest api or filesystem for available environments (for 0.4.x release).

Fixes #1019

Changes:

• added environments from qhub-config.yaml to cdsdashboards list.
