ls-remote may or may not operate within a repository, and as such will
not have been initialized with the repository's hash algorithm. Even if
it were, the remote side could be using a different algorithm and we
would still want to display those refs properly. Find the hash
algorithm used by the remote side by querying the transport object and
set our hash algorithm accordingly.
Without this change, if the remote side is using SHA-256, we truncate
the refs to 40 hex characters, since that's the length of the default
hash algorithm (SHA-1).
