Android: Issues with SetupCommentSectionTask

This fixes the second most reported force close.

For some reason the replyUser cursor does not always contain data. I saw this consistently when loading the "Three Months To Scale" entry on the Newsblur blog. I'm not sure what the source of the problem is but at least now it won't crash the app.

I also commented out adding user images next to comment/shared counts and for liked comments. 

When there were a large number of shares/comments the images all seem to display vertically on my phone. Given the smaller screen real estate I don't really see any benefit in displaying user images in the app.

User images with likes were being displayed over text. Again, with reduced screen real estate I don't really see the benefit of showing images here.

(Note that I meant to submit the force close fix and formatting changes as two pull requests. I didn't realise that github would automatically add the second commit to the open pull request)
