[FIX] website: multi-solve multi-website's multi-write

The write method did not work properly for views anymore as soon as it
was called on a multi-records recordset which contains at least one
view which is not website specific. In that case, it used the cow
system for that view (and thus created a specific copy)... but forgot
to continue the write method for the other views, leading to strange
results.
