normalizeSuperJsonDocument function and hidden env variables resolution

[freaz]

It is easy to miss, that without passing environment to the function env variables won't be resolved.

Main issue I see, is not expected behaviour inside SuperJson normalization.

Expected Behaviour

Not sure what would be the best, but can imagine one of the following solutions:

1. environment will be mandatory parameter
2. environment variables resolution will happen in separate function

Current Behavior

Silently skips resolution.

Possible Solution

Not obligatory, but suggest a fix/reason for the bug
