Fix the issue with relative Events import from snarkyjs

[maht0rz]

Currently we import some internal SnarkyJS packages relatively from node modules. This wont work for projects installing our packages.

This jest config is a temporary solution until Events are exported from snarkyjs:

We should make a PR to snarky to get rid of this issue.
