Use Doctrine for the opens and clicks exporters

This commit refactors the code that handles exporting e-mails opens and
clicks when generating the personal data file to use Doctrine instead of
Paris. I opted to do this in this task as opens and clicks code share
some functionality, and I didn't want to add more code that relies on
Paris, as we are eventually going to remove it.
