Merge branch 'sg/object-as-type-commit-graph-fix'

The commit-graph facility did not work when in-core objects that
are promoted from unknown type to commit (e.g. a commit that is
accessed via a tag that refers to it) were involved, which has been
corrected.

* sg/object-as-type-commit-graph-fix:
  object_as_type: initialize commit-graph-related fields of 'struct commit'
