Fix storyshots renderer and serializer options

[theneva]

What I did

Fixed passthrough of options from initStoryshotsto snapshotWithOptions. In practice, this makes it possible to send renderer and serializer as options in the intended way (as documented in storyshots' README).

How to test

I've updated the snapshots from storyshot.enzyme.test.js which uses a custom renderer (enzyme's mount) and serializer (enzyme-to-json).

Edit: CI is red due to some kind of versioning errors. I don't know what causes that, since my branch is not behind master. I'll be happy to fix it if someone points me in the right direction :)
