Subject: [PATCH] test: give each reload test file its own CSS fixture

`api-plugin`, `event-source` and `hot-and-live-reload` all rewrote
`test/fixtures/reload-config/main.css`, and `node --test` runs files in
parallel, so a test could see another file's colour or an extra rebuild.
Give `api-plugin` and `event-source` their own copies, as `progress`
already does with `reload-config-2`.
