fix(test-tooling): uncomment code that was forgotten

During testing it was easier and faster to have the
cordapp building process commented out because
the obligation cordapp is pre-built within the
container image of AIO Corda, then it was forgotten
like that which is not good because the rest of the examples
are not pre-built and therefore don't actually work
without this line being uncommented.
