🐛 Adjust records generated during view change so their date matches the view date

[amortemousque]

Motivation

Currently, when a new view is generated we get the current timestamp to define the view date.
Then we take a full snapshot, which consists in 3-4 records every time a record is emitted, we get the current timestamp to define its date

This causes an issue during replay, when seeking: when the user clicks on a View event, the player actually shows the previous view, because the records corresponding to the new view are a few milliseconds after the view start.

This PR set the view date to the fullsnapshot emitted records when a view change
