[FIX] web: various fixes with one2many/formviewdialogs

We share the basic model record between views, and we have to make sure
that everything is properly coordinated.  The main issue solved by this
commit is the fact that we can now edit a one2many record, then close
the dialog, then edit it again and finally cancel the changes, which
bring us to the previous step.

Also, we had to slightly improve the AbstractView API
