Update circuits.js tests and run in CI (#167)

* Do not use random values for snapshot tests

* Add circuits.js to CI

* Run circuits tests sequentially to avoid sync wasm access errors

* Skip failing VK deserialization test

* Remove unused import

* Update abis snapshot

* Skip failing tests for the time being

* Prettier

* Fix formatting

* Update dockerfile for circuits js
