Fixes several cases where we access an undefined value.
In the case of
lastFullSnapshotEvent
, it can be undefined if we receive an incremental event before a full snapshot. This can happen, for example, if a user refreshes while canvas worker is working and on reload it finishes to call the mutation callback and before fullsnapshot occurs.Fixes JAVASCRIPT-2S3R
