Subject: auto generated vf module index param

added test for when this is the first vfmodule added
unit test no longer tests already created vnf
refactored test to be more clear about uuid grouping
Added javadoc for getLowestUnusedVfModIndex method.
Increment index by vf module model invariant uuid
Fix unnecessary whitespace delta for GenericVnf file
Fix GenericVnf and modify junit for setting vfmodules
