The new NHS Login tests are dependent on this change to the api_test_utils library and may not run green until the release is completed.

Previous issues with builds failing during make install appear to have been caused by an issue with how poetry handes pip and setuptools in versions prior to 1.2.0a1:
python-poetry/poetry#3153
python-poetry/poetry#4242

This has been fixed as of this PR, that is included in version 1.2.0a1 onwards:
python-poetry/poetry#2826

The removal of references to setuptools within the poetry.lock file in 6143369 is a workaround to fix this issue in older versions of poetry without the above fix merged in.
