test: Do not press tab when no results matched
test: Do not press tab when no results matched

When typeAhead select has some options and 'tab' is pressed then the
first option is picked. However, when no matches are found, then tab
just navigates to another element. This worked on chrome due some timing
magic. I also bumped the timeout to make it more predictable.
