Revert "#391 Database/Element class now has correct type for localname"

This reverts commit 59cd068

Turns out this is an issue in the Manage API - when multiple values exist for a localname, the JSON representation expects an array of strings, while the XML representation expects a single string. Will file a bug with ML.
