we don't currently support reading a remote Dockerfile with a local
context when doing a remote invocation because we automatically derive
the dockerfile from the context atm. To avoid mistakenly reading a local
Dockerfile, we check if the Dockerfile exists locally and if so, we
error out.

Fixed in 12b6a3ad9aeda4bdf67a6a55d22fc43594125ec4, but now we have
regression tests! So we can add a check that we don't break this
behavior again.
