[PATCH v2] fetch-pack: fix object_id of exact sha1

[Gabriel Souza Franco <gabrielfrancosouza@gmail.com>]

Commit 58f2ed0 (remote-curl: pass ref SHA-1 to fetch-pack as well,
2013-12-05) added support for specifying a SHA-1 as well as a ref name.
Add support for specifying just a SHA-1 and set the ref name to the same
value in this case.

Not the cleanest conditional I've ever written, but it should handle
all cases correctly.
