Use relative path to change to conda/js dir during test
This MR removes the RECIPE_DIR
environment variable use during test. Such value may change depending on the docker CI the test is running. If the value is different than that used during the build phase, then the build fails.
Example: https://gitlab.idiap.ch/beat/beat.editor/-/jobs/158178
It also makes the built package more relocatable and about 10x smaller!
