template_resolver fails on empty object-templates-raw fields

[bobh66]

When running template_resolver on a policy from an existing cluster, it may encounter object_templates_rawset to an empty string. This can happen when a conditional policy template for a cluster results in no policies being created. This is a valid scenario on the cluster but template_resolver has an explicit check in processObjTemplatesRaw() for an empty object-templates-raw string value and returns failure.

This blocks processing of the rest of the policies instead of just ignoring the empty template.

If it's acceptable I can push a PR to have the function return nil on an empty string value for object-templates-raw so that it can continue to process the rest of the policy.
