S-48712
- Refactored githubhelper so it follows the async pattern. Instead of pushing inside the library now it is specified in a callback.
- Changed some functions signatures so they take objects as parameters instead of a fixed number of them.
S-48712 replaced nock for proxyquire.
S-48712 changed [] to undefined since that is what we get when a stream for an asset does not exist.
S-48712 First tests for eventStore.js
