External CVoc - indexing can fail for single valued fields

[qqmyers]

What steps does it take to reproduce the issue? Configuring a CVoc script on a field that is not multivalued will fail if the script is configured to add more than one value to the index, i.e. it adds both the identifier and a name, or includes translations. An example would be using the depositorOrcid example :CVocConf setting.
