* Site searches will set idaction=0, which is actually a valid entry page url, so we test specifically for false
* Add test case where the visit directly starts with an event

-> the pageview will be set as the entry page
* Update processed api responses
* UI tests: two new fields in log_visit have been updated
* Processed API responses
