fix(date-picker): avoid closing before input click

[vicgeralds]

When the date picker is already open, clicking the input field (or tabbing to focus the clear button) would first hide the date picker on mouse down and then show it again on mouse up.

This is fixed by ignoring mousedown events from the input field. We also don't need to listen to keydown events, since we're already hiding the date picker on blur.
