Fix tab => direction keys handling with disabled search

[zoglo]

Description

This is a continuation of #1242

Whilst the PR in #1242 did work, we forgot the case that a choices may not have an input field when the search is disabled.
Without a search input, we are not closing the dropdown if it has been open when tabbing away.
