…se previous release of epicscorelibs

This test can be enabled now that we are using correct pyca package from
conda. (was done in commit:

Installing correct library and enabling test fixes issue where a user
downloads pydm and runs the tests with pytest cmd directly (instead of
run_tests.py), only to see 'no module named psp' failure. This failure seems to suggest
to user to 'pip install psp', which is entirely the wrong package and
just leads to further confusion.
