#1 getDetails() does not report all actions

[DucHoaiNguyen]

This problem happens only with action coverage (other types of coverage are ok)
- The getDetails() method returns only the actions which are covered >0 times. I expect it to return coverage info of all actions, including the ones which are not covered. This information is very important for testers to diagnose why some actions are skipped by the tests. With other types of actions (e.g. state coverage), this method returns all items, including the ones that are not covered.
