The latest refactoring in a445278 kept some factorizations that are
not legit anymore after the refactoring.
It is also cleaner to not make serializer choice in the list view if
the reason for this choice is related to something else b/c other
views would then use the wrong serializer and that would be a
security leak.
This commit also fixes a bug in the access rights inheritance: if a
user is allowed to see accesses on a document, he should see all
acesses related to ancestors, even the ancestors that he can not
read. This is because the access that was granted on all ancestors
also apply on the current document... so it must be displayed.
Lastly, we optimize database queries because the number of accesses
we fetch is going up with multi-pages and we were generating a lot
of useless queries.
