I don't think it works if you're already a human, as you've already got that bonus feat. Sort of like if an Elf wild shapes into another Elf, they won't get an additional +2 to listen, search, and spot.

However, if you're not already human you'll also get the bonus skill points! So if you need to make a particular skill check, Wild Shape into a human, use that bonus feat to make it a class skill or just get Skill Focus if it already is, put max ranks in it, then make your check.
