[REF] test_main_flows: use XMLID's as app menu selector

Note that tours shouldn't be language dependent.
By using XMLID's we are able to find a menu even if the tour
is running in another language.

The tip has been moved slightly but it's not a big deal,
others selectors menu already used XMLID's.
