clone: do faster object check for partial clones
For partial clones, doing a full connectivity check is wasteful; we skip promisor objects (which, for a partial clone, is all known objects), and enumerating them all to exclude them from the connectivity check can take a significant amount of time on large repos. At most, we want to make sure that we get the objects referred to by any wanted refs. For partial clones, just check that these objects were transferred.
