If we had a name that is translated in the template files with the base
locale instead of the fully qualified one (i.e. `fr` instead of
`fr_BE`), we would only store `fr`, which the ORM doesn't understand as
there is no fallback on the generic locale (only on `en_US`)
Instead of storing the translation values straight out of the record's
values dictionary, we are now doing something similar as the generic
`_load_module_terms`, loading only the languages being installed, and
using the fallback on the generic locale there.
