Description of problem:
No flash message is displayed when you try adding a class with a duplicate name. Other automate objects show this message as expected.

Version-Release number of selected component (if applicable):
5.8.0.2

How reproducible:
always

Steps to Reproduce:
1. Create a class
2. Try creating a class with the same name.

Actual results:
You stay on the same page, no flash message

Expected results:
You stay on the same page, flash message informing you about the fact that class with such name already exists.

Additional info:
It has the correct functionality - it does not create a duplicate class. It is more about the fact, that it does not tell the user what happened.
