fix: source coverage ci failure (#5209)

Description
---
Don't run cucumber during the coverage runner. It always returns a non 0 exit code when additional cucumber params aren't passed making CI think it's a failure.

Motivation and Context
---
After PR's get merged the coverage ci fails: https://github.com/tari-project/tari/actions/runs/4281676173/jobs/7454994490
