Subject: getFileVersionHistory doesn't work if information is hidden
Original description:
Take a file where some information is hidden, for example this one:
https://commons.wikimedia.org/wiki/File:Catania\_Piazza\_Quattro\_Canti.jpg
In this case, the edit summary for the first revision is missing.

Try this code:

import wikipedia
site = wikipedia.getSite\(u'commons', u'commons'\)
page = wikipedia.ImagePage\(site, u'File:Catania Piazza Quattro Canti.jpg'\)
history = page.getFileVersionHistory\(\)

I get an error message:

Traceback \(most recent call last\):
File "<stdin>", line 1, in <module>
File "wikipedia.py", line 4194, in getFileVersionHistory
result.append\(\(i\['timestamp'\], i\['user'\], u"%s×%s" % \(i\['width'\], i\['height'\]\), i\['size'\], i\['comment'\]\)\)
KeyError: 'comment'

There is no i\['comment'\] because the comment is hidden \(deleted\).

Result: The script crashes when running getFileVersionHistory. It would be better if getFileVersionHistory at least returns what's available, instead of returning nothing at all. For example, if you use i.get\('comment'\) instead of i\['comment'\], then getFileVersionHistory returns None if there is no comment. That seems much better than crashing.
