Building snap locally takes over 3 minutes

It appears that we don't have a watch command setup for the snap when running yarn demo, we should speed up the snap build command before we add watch so that it can be useful for local dev.

Pretty sure ses eval takes the longest, it could be disabled but there is a risk, Metamask won't install snap.
