The same optimization in dfa33a298d ("clone: do faster object check for
partial clones", 2019-04-21) can be applied to fetch as well, so this
patch set does so. Patch 1 makes the check more robust, and patch 2
applies it to one of two connectivity checks performed during the fetch.

As mentioned in patch 2, when fetching from a local repo, I got a
speedup of 6.63s to 3.39s.

  connected: verify promisor-ness of partial clone
  fetch: forgo full connectivity check if --filter
