after odoo #113888
when copy translations from one record to another, translations for
non-installed languages may raise error.
These translations may be
1. created before the langauge is deactivated
2. en_US which is always available for non falsy translated field value
this commit drops translations for uninstalled languages except 'en_US' when
copy and prevents raising error when users want to translate en_US when en_US is
not activated
