exchange: fix test for remote support of binary phases If the remote do not support phases, the "get" call will return None. We change that default return to empty tuple to fix the membership testing. This was a bug in the initial series. Thanks to yuja for catching this.

exchange: perform stream clone with clone bundle with --uncompressed Previously, `hg clone --uncompressed` would always clone from the origin server, even if a streaming clone bundle were available. With this change, we invoke the clone bundle mechanism before the stream clone mechanism, giving clone bundles the opportunity to handle --uncompressed (which is mapped to pullop.streamclonepreferred). The clone bundle filtering code now filters out entries that aren't stream clones when a stream clone is requested. If a stream clone clone bundle entry is present, it will be used. Otherwise, the client will fall back to a server-based streaming clone. .. feature:: `hg clone --uncompressed` uses clone bundles when possible Differential Revision: https://phab.mercurial-scm.org/D833

tests: add tests for clone bundles with --uncompressed Currently, --uncompressed will always clone from the origin server, even if a stream clone bundle is present. Let's add tests demonstrating this behavior. Differential Revision: https://phab.mercurial-scm.org/D832
