[Enhancement] Aggregate "Unknown" device within custom reports as well

[SW-Vincent]

The device category "Unknown" is currently not displayed within custom reports.

Summary

While "Unknown" devices can be interpreted as null values (just as Non campaign visits for campaign name dimension) it is a slightly different case : the sum of device types is expected to be the total, otherwise it creates biases in data lecture and makes it harder to combine data from different reports.
Here are the main consequences (direct and indirect) :

• sum of rows not matching totals (while it is expected to)
• missing subrows for unknown devices
• makes processing data on a data visualisation Tool over a common dimension less accurate

Thanks for reporting this @SW-Vincent, unknown devices are already aggregated in the dashboard widget, so it makes sense to me that this should be consistent in custom reports and have all the rows correctly sum up to the total.

I'll assign this issue for prioritization by our product team.
