Problem/Motivation
Retrieving counts of source data when the source data can include translations is troublesome. It isn't possible to just call `$this->query()->count()->execute();` That won't return anything but the main translation count.
Proposed resolution
Add logic to the count method so that when translations are enabled (include_translations: true) the count returned is the number of items in the iterator.
