[FIX] TopBar: Remove hidden functions from the insert menu

The introduction of the `hidden` tag of functions in pr #1928 did not
account for the `insert function` menu of the top bar that was
developped at the same time.

This revision ensures that the functions marked as `hidden` do not
appear in the top bar menu, similarly to their behaviour in the composer
formula autocomplete assistant.
