function EntityAutocompleteTest::testSubmitDriven

Test the behavior of the submit-driven AJAX example.

Behaviors to test:

• GET the route ajax_example.autocomplete_user.
• Examine the DOM to make sure our change hasn't happened yet.
• Send an event to the DOM to trigger the autocomplete.
• Wait for the autocomplete request to complete.
• Examine the DOM to see if our expected change happened.
• Submit some names to see if our form processed the user properly.
