[webapp-container] When sharing a photo to facebook, a "Ubuntu Web App" album is created and used as the target

When sharing a photo to facebook through the content hub, once the upload is successful, one can notice that the photo had been automatically added to an album called "Ubuntu Web App".

It seems that the creator of the OAuth token (that acts on behalf of the user), is used as the name of the album for the upload.

I couldn't find a reference in the graph API reference anything about that specific behavior:

https://developers.facebook.com/docs/graph-api/reference/v2.6/photo

This comes from a user report that also mentions a few extra elements that I havent noticed in my tests, here it is for reference:

"When you upload a photo to facebook the web app adds a hyperlink with the text "Ubuntu Web App" which takes you to http://not.a.real.website.com/ which redirects you to Website.com."
