[PATCH 07/11] convert has_sha1_file() callers to has_object_file()

[Jeff King <peff@peff.net>]

The only remaining callers of has_sha1_file() actually have an object_id
already. They can use the "object" variant, rather than dereferencing
the hash themselves.

The code changes here were completely generated by the included
coccinelle patch.
