[FIX] website: perf - prefetch access token to avoid extra request
[FIX] website: perf - prefetch access token to avoid extra request

Access_token has a restricted group, so it not fetched by defaut.

In our case, we know that after the first access to partner_id, that will fill
the cache without access_token, we will access access_token (so new query).

So we access first the access_token, to have only one request that fill the
cache with the access_token, and the partner_id used later.
