[FIX] web: FormRenderer: notebook and invisible pages

When switching between records, the active tab of the previous
record is made active on the new record.

However, before this rev., this was done without checking that
this tab is still visible on the new record (there may be an
invisible attrs that makes it invisible), so it happened that
the active tab was actually invisible.

This was for instance the case when switching between stock
pickings, as the first tab ('Operations') is sometimes hidden.
