Refresh hydrations

Thanks for contributing to Toucan. Before open a pull request, please take a moment to:

• [x] Ensure the PR follows the Clojure Style Guide and the Metabase Clojure Style Guide.

• [x] Tests and linters pass. You can run them locally as follows:

  lein test && lein lint

  (CircleCI will also run these same tests against your PR.)

• [ ] Make sure you've included new tests for any new features or bugfixes
• [x] New features are documented, or documentation is updated appropriately for any changed features.

• [x] Carefully review your own changes and revert any superfluous ones. (A good example would be moving words in the Markdown documentation to different lines in a way that wouldn't change how the rendered page itself would appear. These sorts of changes make a PR bigger than it needs to be, and, thus, harder to review.)

  Of course, indentation and typo fixes are not covered by this rule and are always appreciated.

• [x] Include a detailed explanation of what changes you're making and why you've made them. This will help us understand what's going on while we review it.

Once you've done all that, open a PR! Make sure to at-mention @camsaul in the PR description. Otherwise I won't get an email about it and might not get review it right away. :)

Thanks for your contribution!
