[FIX] website_crm_partner_assign: foolproof translation for partner lvl

To reproduce the issue:
1. Add French as a language to your profile
2. Install [CRM], [Resellers] on Apps
3. On [Settings]>[Website]
- set the language to French then SAVE
4. Go to [CRM]
- click [Configuration]>[Partner Level]
- click Gold
- click [Go to Website] at the top right corner
- adjective and subject order is not natural for French speakers

Desired behavior: Remove the word 'Partner' (show level only)

Impacted versions: 14.0 up to master
