[FIX] mail: chatter in x2many form view

Since rev. 755a8d815a, it crashed when the user tried to open an
x2many record in form view (thus in a dialog), if there was a
chatter in that form's arch.

This was because the wrong viewType was used (for instance, list
or kanban instead of form), to look into fieldsInfo, and thus the
chatter fields couldn't be found.
