TestDPC replica show all delegations

If the TestDPC replica app is the delegated
app, show all delegations. Do not call
isManagedProfile(admin) as the admin is null
for the delegated app.

Manual testing
- Set TestDPC as the device owner
- Delegate security logging to TestDPC replica
- Select 'Generic delegation' in TestDPC replica
- Verify an exception is not thrown
- Verify all delegations are shown and security
  logging is selected.
