Proposed patch

I'm running https://code.google.com/p/wikiro/source/browse/trunk/robots/python/pywikipedia/diacritice/diacritics_redirects.py on ro.wp. The put function throws a KeyError:

>>> Comuna Adâncata, Ialomița <<<
[[Comuna Adâncata, Ialomiţa]] doesn't exist
Do you want to create a redirect? ([y]es, [N]o, [a]ll, [q]uit) y
{}

KeyError: 4164884

The error is caused by the _revisions dict not being populated. Possible patch is attached.
