stream-clone-test: simplify the case where server disabled it

We have an option to disable it, we don't need to test it with all protocol
variants.

In addition there is little value in looking at the bytes to bytes details of
the reply. Such check is very fragile and consume a lot of time for little
value when adjusting formats, caches, and protocol.

Check local clone
==================

The logic is close enough of uncompressed.
This is present here to reuse the testing around file with "special" names.

  $ hg clone server local-clone
  updating to branch default
  1088 files updated, 0 files merged, 0 files removed, 0 files unresolved

Check that the clone went well

  $ hg verify -R local-clone -q

Check uncompressed
==================

Cannot stream clone when server.uncompressed is set to false
------------------------------------------------------------

When `server.uncompressed` is disabled, the client should fallback to a bundle
based clone with a warning.

The warnings filtered out here are talking about zero-length 'orphan' data files.
Those are harmless, so that's fine.
