[FIX] website: conditional_visibility_1 tour breaks when option hidden

In the conditional_visibility_1 tour, when setting up the UTM Medium,
the "Email" value is searched for.

But if more records (like with the design-themes testing enabled) push
this value out of the autocomplete initial proposition, the value cannot
be selected.

This commit fixes it by adding a step that search for the "Email" value
to ensure it is in the autocomplete propositions' list.
