[FIX] web: click on wrong options in autocomplete

The purpose of this commit is to fix an indeterminate error in
the test_03_sale_quote_tour.

Error: UncaughtTypeError: Cannot read properties of undefined (reading
'unselectable')

Why:
In the autocomplete component, it is possible to replace the sources
without it being rerender. It is therefore possible to click on a option
that no longer exists in the component's internal state, which causes
the crash.

Solution:
We wait that all the sources are loaded before replacing them.
