French translation - important mistakes
**Describe the bug**
1) The "Buy/Sell" button on home page is translated as "Echange" but it's very confusing for people (with "Echanger" button = Swap)
2) When creating a wallet, when the mnemonics are displayed, the "Show me the seeds" is translated like "Show me your jerk" somehow

**To Reproduce**
Steps to reproduce the behavior:
1. Go to Parameters
2. Change to French langage
3. Go back to Home screen
4. See error on bottom right button

**Expected behavior**
1) The bottom right  "Buy/Sell" button should be translated as "Achat/Vente" or "Acheter/Vendre" even if it's longer than usual.  (and "characteristics" by "services")
2) The seed verification button should be translated as "Vérifier les mots-clés" or "Vérifier les mots-clés (seed)"
