[FIX] web: translation: don't reset database on `set_bundle`

set_bundle is called twice (one time by the session, another time
by the web_editor). As the `set_bundle` actually drop the dict of
translations instead of updating it and as web_editor only load
the terms of its module, depending on which call to `set_bundle`
ends first result on having your translations or not.

This commit update the database of translation instead of dropping
it, which fixe the current issue (the dict of traductions empty of
the traduction you really need) but another fix would be to remove
the useless call by web_editor when launched in the backend  (which
is probably there because it was needed when the web_editor was only
working in the website).
