Consider calling rendering with current jest.config

[siebigteroth]

Currently, the configured jest.config isn't considered when creating snapshots. Therefore, e.g. styled-component serializer is ignored, if configured. Issue #30 is similar, but doesn't consider existing configurations.

Sounds reasonable. Would you like implementing this change? We could leverage jest-config for that. This would require adding it as a dependency or a peer dependency.

maybe we could somehow pass in the config so you could delegate to other serializers first, then do your diff?

@siebigteroth FYI, we just released v0.6.0 with setSerializers API, which can unblock you: https://github.com/jest-community/snapshot-diff#custom-serializers
