[14.0] account_analytic_tag_default overwrites existing analytic tags when updating account move line

[remi-filament]

Module

account_analytic_tag_default

Describe the bug

When updating account on account move line (for instance from Invoicing > Accounting > Journals > Purchases), the analytic tags are replaced by the default one from analytic account (none if none is set).
Have a look at this video reported when testing #497 which is not linked to added module but to account_analytic_tag_default instead :

Expected behavior
If existing, analytic tags should not be overwritten
