Add failing star selector to tests.

[aldhsu]

Hi @AleshaOleg, I was trying to use stylelint and found this problem with the * selector. I might attempt to fix it later but I might not get to it.

Nevermind. I think I will need to do some more investigation into the source of the error.

@aldhsu hey! Can I help you? Please send me an example of how you're using stylelint, and I will try to reproduce

[AleshaOleg]

Actually, you're right. postcss-sass now don't have any tests for *. I'll do it.

Just added test - 88d6e46

Seems it's working fine🤔

@AleshaOleg thanks for the quick reply. I jumped to conclusions. Had nothing to do with post-css was the parser gonzales-pe.
Was something like this:

*, 
*:before, 
*:after,
   box-sizing: inherit

Which sounds like this issue tonyganch/gonzales-pe#238.
The error was happening at the *, but the problem is actually at *:after,.

@aldhsu ok, sorry. Nothing I can do there.
