Description of problem:
Upon deletion of a system template, sometimes the UI pops up a confirm button that, when confirming, causes a UI error. Additionally, sometimes the left pane does not reset, returning to the "home" breadcrumb, but this is harder to reproduce

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


How reproducible:


Steps to Reproduce:
1.  Sync RH content
2.  Create a new template, "blah"
3.  System Templates (left pane) > Products; in the search box, enter "R" and select one of the resulting products; +Add
4.  Click the remove button at the bottom of the pane (not the product 'Remove' link); confirm
5.  View secondary confirm button that appears ("Save Changes", "Discard Changes")
6.  Hit "Save Changes"
  
Actual results:
* Most of the time - Error box requiring page reload.
* Occasionally (haven't figured out the heuristic) - template gets removed but left pane does not update - still shows items in various states of +Add / +Remove

Expected results:
I don't think we should be seeing this at all. I think this is an artifact of modifying an unsaved template.



Additional info:
The error message sometimes seen is similar to that of bug #751159
