There was a bug that was making the code use the wrong filter
and thus the wrong SQL query for the "# number of machine opens"
segment. Resulting in the wrong subscribers being associated with this
segment.
The email() method of the FilterFactory was using the wrong check to
decide which filter to use for this segment (the filter should be
EmailOpensAbsoluteCountAction and the factory was using EmailAction).
This commit fixes this problem.
