Adding tests. DeployOnlyServer does not explicitly set its default publish type to "local". Since older deploy-only servers will not have this attribute, simply adding it as a new param is not sufficient. Older servers must continue to work. This requires new tests and minor code changes to ensure defaults are provided.
