change(rendercomment): converted to use aurweb.db ORM

- Added aurweb.util.git_search.
    - Decoupled away from rendercomment for easier testability.
- Added aurweb.testing.git.GitRepository.
- Added templates/testing/{PKGBUILD,SRCINFO}.j2.
- Added aurweb.testing.git.GitRepository + `git` pytest fixture
