typeahead: Fix buggy advanceKeyCodes code.

The `advanceKeyCodes` option was introduced in #10092.
It included a buggy check for `$.inArray` that returned
a falsey value only when the keycode was the first
element of `advanceKeyCodes`.

Because the only instance of `advanceKeyCodes` right now
is for search and contains only one element, this change
is functionally equivalent.
