Description of problem:
After a user has added content to a system template and hit the 'save' button, hitting the 'home' icon on the system templates pane prompts user to save, noting there is (apparently??) unsaved content. This is already confusing enough, but  hitting "Discard Changes" then shows "Saving System Template" on UI. 

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


How reproducible:


Steps to Reproduce:
1.  Add RH content via cert
2.  Create a new system template, "test system template"
3.  Content Management > System Templates >     Red Hat Enterprise Linux Server > Red Hat Enterprise Linux Server Package Groups
4.  Choose your $template from the right pane
5.  Navigate to $template > Package Groups
6.  From left pane, Add a few package groups to the system, i.e., Base, Chinese support, Compatability Libraries, assuringthe groups you just added show up in the template.
7.  Hit the Save button for system template; note it grays out.
8.  Hit the Home icon in the system templates pane breadcrumb div



Actual results:

* Dialog box appears asking user to save unsaved changes.
* Hitting "Discard Changes" nonetheless shows "Saving System Template " on the screen

Expected results:
* Shouldn't see this in the first place if there's nothing new to save
* Discard shouldn't be indicating that we're saving anything

Additional info:
In some cases I saw the UI kind of lockup and get confused after doing this, but it may just be due to the massive amount of data in the RH cert.
