/*
* Note content has quite special handling - it's not a separate entity, but a lazily loaded
* part of Note entity with it's own sync. Reasons behind this hybrid design has been:
*
* - content can be quite large and it's not necessary to load it / fill memory for any note access even if we don't need a content, especially for bulk operations like search
* - changes in the note metadata or title should not trigger note content sync (so we keep separate utcDateModified and sync rows)
* - but to the user note content and title changes are one and the same - single dateModified (so all changes must go through Note and content is not a separate entity)
