tests/cli: ignore user's RUST_LOG= environment variable in tests nixpkgs build system sets `RUST_LOG=` (empty value) by default. This switches `mdBook` into warnings+ mode (instead of info+). This causes the following tests to fail: $ RUST_LOG= cargo test --test cli_tests ... cli::test::mdbook_cli_can_correctly_test_a_passing_book cli::test::mdbook_cli_detects_book_with_failing_tests cli::build::mdbook_cli_dummy_book_generates_index_html The change drops RUST_LOG= entry. 2022-03-31 07:02:53 +00:00			`use assert_cmd::Command;`
