V622-017: Fix env grouping with non-default metadata.

The routine for grouping lexical envs would previously always flatten grouped
envs. However, this process would discard the `default_md` field of the nested
grouped envs.
The implementation now decides to flatten grouped envs only if the resulting
env behavior is the same.
