Previously, to retroactively add filter to an existing (shallow) clone
one would have to manually change the repository configuration to make
git to believe that there was an existing promisor, like:

  git config core.repositoryFormatVersion 1
  git config extensions.partialClone origin
  git fetch --unshallow --filter=blob:none origin

Because the code can already set up promisor, it would be safer and more
convenient to just do that in git itself.

This version of change will also prevent the code from making damaging
repository upgrades (when non-standard extensions exists) as pointed out
by earlier reviewers.
