Title: BUG: javascript tree node updating fails when Translatable is used

Automatic tree node updating fails when for example creating a new
translation, due to the update URL containing two question marks,
due to the locale get parameter.

Fixed by using the $.path.addSearchParams utility function, which properly
checks for existing query string parameters.
