Rename custom module directories

- Rename `opdavies_blog` to `blog`.
- Rename `opdavies_blog_test` to `blog_test`.
- Rename `opdavies_talks` to `talks`.
- Rename `opdavies_talks_test` to `talks_test`.

The files within the directories haven't changed, so there is no
breaking change caused by renaming the directories.
