Fix API to retrieve URL to Spreed WebRTC
Fix API to retrieve URL to Spreed WebRTC

If Spreed WebRTC and Nextcloud reside on different origins, a file
"OwnCloudConfig.js" is required. If this file exists, said API
endpoint erroneously did include "?load_config_js=1", a flag to
signal the load of that .js file to Spreed WebRTC.
