Bug in the post series widget

[Ryan Lerch]

Hi all,

just a heads up there is a bug in the post series widget that shows the 
posts in the sidebar even if they arent published publicly.

I'll try to get a fix for this done this week, but in the meantime, we 
can work around this issue by only adding the post to the post series 
just before publishing.

cheers,
