ParseRequestedAdminRights was missing post_stories, edit_stories and
delete_stories identifiers, causing all admin rights to be discarded
when any of these appeared in the admin parameter. Also, startchannel
always used explicit URL rights even when empty, never falling back to
bot's default admin rights configured via BotFather (unlike iOS client).
Unknown admin right identifiers are now skipped instead of discarding
all already-parsed rights, improving forward-compatibility of deeplinks.
