Added an active field track if an Enumeration is active on the frontend view.

* Changed TimelogHelper#activity_collection_for_select_options to only use
  active TimeEntryActivities.
* Changed TimelogHelper#activity_collection_for_select_options to return a blank
  option if the time_entry's current activity is inactive.
