[Bug] "Purchased Products" column always empty for "Sales by Pages" ecommerce reports

[9joshua]

What happened?

The reports in Ecommerce -> Sales -> Sales by Pages includes a column for "Purchased Products". This column always shows zero regardless of reality...

Sales by Referrers do show this data:

What should happen?

Either the "Purchased Products" column should show which pages led to how many products purchased or the column should be removed.

How can this be reproduced?

View the "Products Purchased" column for any report under Ecommerce -> Sales -> Sales by Pages

Looking at the code it seems that metric simply isn't stored for actions. So we either could simply remove the column from being displayed or check if it's easy to process the data for that column correctly.
