ci: Fix init-stage2.sh exit code
After a LAVA job submitter rework, the init-stage2.sh was changed to be
compatible with new LAVA job definitions, but the result from the script
represented by HWCI_TEST_SCRIPT
variable is obfuscated by the set -e
command. So when the test script fails, set
will override the exit
code and the jobs will pass when they should fail.
This MR will also fix the tests expectations and traces that were broken by the CI script bug.
