There is currently a limitation with required fields because an "on change"
compute might trigger the check for "required" before all the actual computes
have been done, leading to the required field check incorrectly failing.
The main goal is to ensure the "on change" computes are done after all the other
computes and after the check for required fields.
A check has also been added to ensure no "real" compute can trigger update cycle
side-effects anymore.
Opportunity is also taken to prevent from checking for required fields on a
record that was deleted as part of the same update cycle.
