Incompetent quality should always set up skills to 'unaware'

[EfimEvgen]

Per CRB 83:

The Incompetent character is treated as having skill level of “unaware” for all skills in the skill group

Yet Chummer doesn't do that, it only bans defaulting, not uses of those skills post-purchase.
It should be fixed by something like how it works with Dedicated Spellcaster? Or disable skills through improvements, I guess?
