Symptom:
Using ERS we can do API calls for different categories:
 user, endpoint, user group, endpoint group, sgt and profilerprofiles

When doing the following, we should get a consistent error code per attempt type:
1. getting the details of a nonexisting name for each category
2. getting all the names on each category, but filtering on a non-existing name
3. deleting a name that doesn't exist on each category

We see a mix of different errors depending on which table we're doing these API calls.

Conditions:
Using API calls to view details or delete items from the DB in ISE 1.2 with names that don't exist in the DB
