Subject: [PATCH] auto-completion: refactor yasnippet config

- Move all setq outside of spacemacs/load-yasnippet
- Explicitly add each snippet dirs, even the one in elpa dir

Before this commit I still get error on yasnippet loading, with this
commit the error is gone.

I hope we get yasnippet loading right this time! :-)
