Add system test to ensure we are getting all conda environments

This is supposed to do the following:

conda create -n "env1" python=x.x
conda create -p "<dir path>/env2" python=x.x
conda create -p "./env3" python=x.x

The environment detection code should find the base and the three above environments.

If we add this test before we remove the env file service, then we can verify if we are getting all of the environments just via conda env list
