[FIX] base: call context_get with the right user

self.env.user returns the current user but browsed with the superuser:
- self.env.user == current user
- self.env.user.env.user == administrator

get_context uses self.env.user to retrieve the context of the user.
Before this patch, the name of the filters was translated in the
language of the administrator instead of the current user.
