One of the indirect callers of make_virtual_commit() passes the result of oid_to_hex() as the name, i.e. a pointer to a static buffer. Since the function uses that string pointer directly in building a struct merge_remote_desc, multiple entries can end up sharing the same name inadvertently.
Fix that by calling set_merge_remote_desc(), which creates a copy of the string, instead of building the struct by hand.
