- cleaned up unused dependencies
- adds missing dependencies that are used in the code
- this should help us be more explicit about the dependencies a package
uses
- because of how the npm scripts were set up, we were running the full
Admin integration tests during the unit tests phase of CI
- this commit renames the majority of `test` to `test:unit` in the
package.json files, and aliases `test` to `test:unit`
- special packages like Admin have no-op'd `test:unit` scripts so we
don't end up running its tests

- the oembed service is completely standalone and could do with some
individual unit tests
- moving it out to a package allows us to draw the boundaries better and
allows us to remove some dependencies from the core package.json
