brian m. carlson bf154a8782 t/helper: make repository tests hash independent
This test currently hard-codes the hash algorithm as SHA-1 when calling
repo_set_hash_algo so that the_hash_algo is properly initialized.
However, this does not work with SHA-256 repositories. Read the
repository value that repo_init has read into the local repository
variable and set the algorithm based on that value.
