[FIX] web: handle empty notebooks in form views

Before this commit, when re-activating a previously active notebook tab, the form
renderer would assume that a tab was actually active. However this does not happen
if no tab is visible or defined and it results in a crash instead.

Now, if no active tab is found, a default active tab (0 = first) is set. This only
helps to prevent the crash and does not affect the current behaviour.

closes odoo/odoo#50006
