Return Updated Projects In Project List Incremental Syncs

project.list incremental syncs now return projects modified since the last sync rather than only projects created since then, and page through them without skipping projects that change while the sync is in progress.
Cursors issued before this change remain valid for full syncs. An incremental sync that was mid-pagination when this change was enabled for your organization will receive invalid_next_cursor once; restart the sync by omitting the cursor parameter. Restarting repeats pages rather than losing data.
