Work around performance issues (timeouts) with happoRegisterSnapshot #43

We are currently seeing the happoRegisterSnapshot call time out in certain test suites. It seems related to the size of the payloads sent over the Cypress websocket -- we've only seen this with pages containing large canvases (that get inlined as base64 images).

I was led to this solution after finding this Cypress issue: https://github.com/cypress-io/code-coverage/issues/76

In that thread, it's suggested that you bypass the built-in serialization and deserialization in Cypress by using JSON.stringify yourself.

Ended up taking a different route.
