Resolve "Publish - upload to S3 stage $IMG_VERSION"
This MR removes any number of ../
from IMG_VERSION
since it is untrusted and can be changed. Confirmed that IMG_VERSION is only set in preprocess in the version.py script. Added a case to the if statement below it to check if the string resolved to "". Several tests were performed locally and I've added them to a comment in the ticket #32 (closed).
**Relevant test job to confirm it works as expected:**
