Moderated lists do not work properly

I decided to test og2list with moderation option on and in the current form the feature is unusable.

Everything went fine as far as receiving a new email, saving it as un-published node and not sending notification at that time.
However, turns out there is no UI for displaying the nodes in the waiting queue. The link "unpublished posts" (in OG block) only shows unpublished comments and not nodes. The module includes a function (og2list_posts_overview) which is documented as a menu callback (never invoked) for displaying unpublished nodes. I tried to call it manually but apparently the code is incorrect since it did not show my unpublished node. Then once I published my node manually (through /admin/node) the notifications did not get sent.

This warrants further investigation. I tested on 4.7 the fix should be done for HEAD / 5.x.
