unittest: Fix clang-tidy-fix

The unittest case for `clang-tidy-fix` checks if the whole project is in
git or not, and skips if not.

Fix this by creating a temporary git repo, copy the test files and run
the tests, following how `clang-format` does.

It also reverts some help code introduced in the previous test.

Tested: Verify the test case passes.
