Fix edition details

[peterstadler]

Description, Context and related Issue

The function edition:details($uri)?name would return an element node instead of a string value, thus the endpoint getEdition.xql returns e.g. "name" : "<editionName xmlns=\"http://www.edirom.de/ns/1.3\">Pintos-Edirom von Salome Obert</editionName>" (among other properties).

This PR fixes this to return only the string value and refactors another function to not duplicate code.

Steps to reproduce

Check the Ajax request to getEdition.xql which is loaded at every star of the Edirom:
