I'm getting different code coverage between 3.3.6 and 3.4.1

# 3.3.6
Coverage report generated for Unit Tests to ./coverage/coverage.xml. 552 / 558 LOC (98.92%) covered

# 3.4.1
Coverage report generated for Unit Tests to ./coverage/coverage.xml. 559 / 566 LOC (98.76%) covered

3.4.1 detects:

• 3 more lines detected in lib/inherited_resources/base_helpers.rb (112 vs 109)
• 2 more lines detected in lib/inherited_resources/singleton_helpers.rb (12 vs 10)

In singleton_helpers, def collection; nil; end does not seem to be covered in 3.4.1, and it looks to be correct, because in 3.3.6

       def collection
-        nil
+        raise
       end

does not raise. So 3.3.6 was reporting wrong coverage

@tagliala thank you. Can you please try removing the nil line so the method just becomes an empty method? It would have the same return value and may appease Codecov here without need for further changes.

Thanks!
