Fix BUILD.bazel style violations (#8081)

`buildifier` was complaining as follows:

    #### :bazel: buildifier: found 2 lint issues in your WORKSPACE, BUILD and *.bzl files
    <pre><code>tests/ts/bazel_repository_test_dir/BUILD:3:1: <a href="https://github.com/bazelbuild/buildtools/blob/master/WARNINGS.md#out-of-order-load">out-of-order-load</a>: Load statement is out of its lexicographical order.
    ts/BUILD.bazel:2:1: <a href="https://github.com/bazelbuild/buildtools/blob/master/WARNINGS.md#out-of-order-load">out-of-order-load</a>: Load statement is out of its lexicographical order.</pre></code>

This can be fixed locally like so:

    $ buildifier -lint fix $(git ls-files | grep -e '/BUILD.bazel$' -e '/BUILD$' -e '\<WORKSPACE$')

I also took this opportunity to fix one of the filenames.

I accidentally introduced these errors in #8078.
