Prior to index v27, there is no project field in the index, so we can't count on the field being present when we need to create a ChangeData from it. Detect this special case and call a new (well, reborn) ChangeData.Factory method with an intentionally ugly name. This sets the project to null initially, and triggers a lazy read from Changes when looking up the project. In addition to the ugly name, check that notedb is not enabled; this is a safe assumption, since the whole point of v27 was to make it possible to read from notedb without reading from the Changes table.

Gerrit Code Review
Gerrit is a code review and project management tool for Git based projects.
Objective
Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.
Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.
