fix(tools): corda AIO healthcheck ignores jolokia errors

The healthcheck script did not fail on curl returning
a non-zero exit code because the bahs script that
does the healthcheck was not configured to do so
leaving the healthcheck essentially broken.
Added the set -e line to the healthcheck to ensure
that this does not happen (it makes the whole script
fail as soon as any command within the script
does so which is what we want from the healthcheck
script)
