[development_environment] Remove prelaunch_test_instance for secret create

The secret is currently created only when prelaunch_test_instance=true,
but barbican validate secret task didn't have that condition but only
rely only on prelaunch_barbican_secret, conditions with this patch
are now synched as prelaunch_test_instance is unnecessary for
barbican secrets.
