[FIX] ir_translation: prevent `overwrite` propagation

Once set for the loading of terms for a lang,
the flag `overwrite` was propagated to all
other following languages, even if not actually needed.

Use case:
 - Installed languages: en_US, de, fr_CH, it
 - Update of the `sale` module
 - In `load_module_terms`, the system iterates through the languages:
   1. en_US: No problem
   2. de: No problem
   3. fr_CH: The flag `overwrite` is set to `True`,
      because the sub-language `fr_CH` should overwrite the `fr` terms
   4. it: The flag is still set to `True`, because of the previous iteration,
      while it must not.
