Odoo 14 introduced the widescale usage of computed fields with readonly=False.
In that case, the compute method functions as a default that can also be used
to compute a value some time *after* the initial creation of the record.
In the OpenUpgrade analysis files, these fields would be misrepresented as
computed fields rather than fields with a default function. This change fixes
that.
Given that the records need to be managed in the modules that own them rather in the modules that override them, and that we also have the noupdate data xml for every module, then we left out the lines that where indicating the override of records.
