Inconsistent behaviour of renderSuggestion query

[jgresty]

There is inconsistency about the query argument passed to renderSuggestion, when there is a value in the input then it works as expected. However when the input field is empty then it receives the value of whichever selection is highlighted.

See codepen: https://codepen.io/anon/pen/wyKgOp

1. Allow shouldRenderSuggestions with empty input
2. Focus on the input field
3. Press Down a few times and observe the query argument passed
4. Clear input and enter a character
5. Press Down a few times and observe the query argument passed

Observed behaviour: Query argument passed is value of selected suggestion when no input is initially empty
Expected behaviour: Query argument passed is empty string when input is initially empty
