angular triggered event log - add template output data

[Lindsay Stratton]

v. 3.8

In the Angular Triggered Event Log, the grid includes a data column Event Template Output, but this displays the action_trigger.event_output.id, not the data.

Displaying the data would improve customer service, such as "Patron says an item was autorenewed, but it wasn't renewed. Is autorenewal configured correctly?" On retrieving the template output, the email notice stated the item could not be renewed.
