Fix multi user notebook (#5563)

* Detect remote changes to notebook object and re-render entries. Detect changes to tags as well

* Do not throw an error when getCurrentUser is called, just return undefined. Code needs a way of testing whether there is a valid user

* Support remote sync of annotations for notebook entries

* Fix bug in notebook spec that prevented multi-user notebook regression being detected

* Fixes edge case where an annotation does not initially exist

* Use structuredClone instead of JSON functions. Fix logical error in entry modification attribution. Address magical value
