test: Remove hard-coded text focus and label for e2e tests (#667)

**What problem does this PR solve?**:
Removes hard-coded text focus and label for e2e tests.

This code took precedent over any configuration provided to ginkgo at
runtime, so only single e2e test matching both focus and labels could
run.

**Which issue(s) this PR fixes**:

root cause.
