commit 16f761349c375d769a7ebd0525b50403ed832acb

Fix DownloadExtensionTest with network service

Also try renabling these tests on Windows since the output from previous flakes was related to
URLRequests which aren't used anymore.

Sheriffs: if these tests flake on Windows, please redisable all the tests via the ifdef that I
removed instead of reverting.
