Dismiss open autocompletes between tests

Clearing the value doesn’t seem to work reliably when the autocomplete is currently open, especially if it has been interacted with (e.g. in a test that sends the arrow down key to focus on a result)

By sending ‘escape’ we dismiss any open autocompletes, which then seems to make the input-clearing work reliably.
