Don't send focus accessibility events when tab isn't focused.

Don't send focus accessibility events when tab isn't focused.

This regressed in r383885 (https://codereview.chromium.org/1815933002).
I meant to check if the focus callback was null, but instead I was
checking if the lazy instance pointer to the callback was null, which
is never true.
