lfs: remove internal url in test

`test-lfs-test-server.t` refers to a FB internal domain and requires certain
implementation (ex. set error code to 404) at that endpoint. Without any
workaround, It should in theory error out like "Domain cannot be resolved".
I don't know how Matt Harbison ran the test.

This patch changes the test to only depend on `lfs-test-server`.
Unfortunately the logic has to be changed since `lfs-test-server` does not
set error code to 404 but just removes "download" from "actions".
