Fix flaky integration test

[szh]

Desired Outcome

Fix flaky tests as seen in Jenkins runs 1056 and 1047.

Special thanks to @ismarc for help diagnosing this issue.

Implemented Changes

Removed | head -1 portion of cli_with_timeout command in TEST_ID_26_helm_override_default_retry_successful.sh. This is not necessary because we're not consuming the value at that point, but rather waiting for the value to appear in the logs. It was causing the command to randomly fail when the value wasn't yet in the logs.
