[PATCH 38/44] remote-curl: avoid truncating refs with ls-remote

["brian m. carlson" <sandals@crustytoothpaste.net>]

Normally, the remote-curl transport helper is aware of the hash
algorithm we're using because we're in a repo with the appropriate hash
algorithm set. However, when using git ls-remote outside of a
repository, we won't have initialized the hash algorithm properly, so
use hash_to_hex_algop to print the ref corresponding to the algorithm
we've detected.
