Fixed a name clash in the 'from_environment_diff' function (#12116)

Browse source 
* Added a unit test reproducing the failure in 12085

* Fixed name clash in the 'from_environment_diff' function

The bug reported in #12085 stemmed from a name clash among variables,
introduced during the refactor in #10753 and not caught by unit tests
and reviews.
