RFR: JDK-8231604: Expand junit test added with JDK-8230920

[Alexey Semenyuk]

Andy,

The test seems to assume particular order of launcher names. Is this 
what we have in jpackage?
I'd rather check the result of AppImageFile.getAddLauncherNames() call 
in the test is a list of two elements and names of launchers are 
contained in the list.
