Always used secret key from current wiki.

Somehing like code bellow needed:

private String getSecret()
{
    XWikiContext context = contextProvider.get();

    try {
        // Current wiki
        DocumentReference configReference = new DocumentReference(context.getWikiId(),
                ONLYOFFICE_SPACE, ONLYOFFICE_DOCUMENT);
        DocumentReference configClassReference = configReference;
        XWikiDocument document = context.getWiki().getDocument(configReference, context);
        BaseObject baseObject = document.getXObject(configClassReference);
        
        String global = baseObject.getStringValue("useGlobalConfig");
        if (!"0".equals(global)) {
            // Global wiki
            configReference = new DocumentReference(context.getMainXWiki(), 
                    ONLYOFFICE_SPACE, ONLYOFFICE_DOCUMENT);

        return secret;
        
    } catch (XWikiException e) {
