hash: require hash algorithm in empty_tree_oid_hex()

Browse Source 
The `empty_tree_oid_hex()` function use `the_repository` to derive the
hash function that shall be used. Require callers to pass in the hash
algorithm to get rid of this implicit dependency.

While at it, remove the unused `empty_blob_oid_hex()` function.
