To prevent external environment variables from leaking into the tests,
which otherwise causes problems trying to write tests for #1011.
Several tests which were relying on this leak had to be fixed, so that
the env vars they were using are set using `ENV_DIR`, as happens in
production.
Fixes#1014.
Fixes#1015.
