Sebastiaan van Stijn b202193ebd Don't mix t.Parallel() wth environment.ProtectAll()
`testEnv` is a package-level variable, so protecting / restoring
`testEnv` in parallel will result in "concurrent map write" errors.

This patch removes `t.Parallel()` from tests that use this
functionality (through `defer setupTest(t)()`).

Note that _subtests_ can still be run in parallel, as the defer
will be called after all subtests have completed.
