Fix interactions tests

These tests were still importing the css files from their original
location. The files were moved in https://crrev.com/c/2810839, but
because of stale `autoninja` compilation outputs, that CL got
submitted just fine. When new bots were provisioned, the files
were missing and the tests started failing post-submit.

Confirmed locally that removing the old compilation output fails
the tests and this output makes them pass again.
