Let's assume a form view with an x2many list, containing itself
an x2many field (no widget, so simply displaying the number of
records). When a record of the list is clicked, a form view
opens and displays the same sub x2many field, with widget
many2many_tags. Both list and form views of the x2many aren't
inline (thus have to be fetched on demand).
Before this commit, it crashed when the user clicked on a row
of the x2many list.
The bug has been introduced by a9cebd5a, which wrongly removed the
code handling this specific situation. At least, now we have a
test attesting that this code isn't useless.
Note that the diff isn't as scary as it looks like (we just added
an if/else, and thus indented the former code inside the else
clause).
