Description of problem:
In advanced options for a kickstart profile, there are some mandatory options marked with asterisk. If user unchecks mandatory option checkbox and attempts to update the kickstart, Satellite will return error about missing mandatory option. If user checks the mandatory option, but leaves text field empty, kickstart file is updated, even if there is no parameter for the options. 


Version-Release number of selected component (if applicable):
spacewalk-java-2.3.8-157.el6sat

How reproducible:
always

Steps to Reproduce:
1. Have a kickstart profile created.
2. Select a profile in Kickstart profiles, go to Kickstart Details -> Advanced Options. 
3. Verify that "auth" option is checked, and delete content of its text field. 
4. Press Update Kickstart button. 

Actual results:
Satellite happily accepts the update and the kickstart file now contains "auth" option without any parameters.

Expected results:
Validating that parameters for each and every (mandatory) option are correct would be almost impossible, of course. Still, there should be at least some kind of warning that option is enabled but without any parameters, and that the resulting kickstart file may not work as expected because of this.
