Support clicking different text for select2 helper

Interaction with the variant autocomplete is not precise. The specs only
search for the product name, then click the first result that matches
the product name which they see.

This could have been the case because searching using the full variant
name does not match the variant. For example, searching "Some Product -
1kg" would not have results, while searching only "Some Product" (the
product name) would list "Some Product - 1kg".

Clicking the first match does not work in all scenarios.

This allows using a separate text for searching and for clicking.
