Description of problem:
 There is bunch of configuration options for JSSE configuration, all empty options are ignored during post-install configuration, but they are shown on Post install summary screen. We should remove all empty options to make the screen more readable.

Version-Release number of selected component (if applicable):
 EAP 6.2.0.CR2

How reproducible:
 Always.

Steps to Reproduce:
 1. Run gui installer, go to Post-Install configuration screen using default values.
 2. Choose to Add a security-domain. Press Next on first Security-domain screen.
 3. On Jsse screen check all available checkboxes and fill some values into all required fields (Keystore/Truststore passwords and URL). 
 4. Press next to go on Post-install summary screen.
