...because patch #849: "iterator for labels_ should be initialized to something" indicated that the code was not nice, even if it was correct. The patch pointed highlighted the bad code style but don't solved the problem. Also add a function allowing to get public label hidden under a team only-label Maybe use it in the not-team-only field of the dialog for this rare case?
