[Media Router] Fixed window refocus problem for filter view input.

[Media Router] Fixed window refocus problem for filter view input.

This change fixes the following case:
 1. The user enters filter view.
 2. The user presses the Escape key which leaves filter view but keeps keyboard
    focus on the search input.
 3. The user focuses another window and then returns to the media router dialog.
 4. The dialog automatically switches to filter view.

The dialog should not be triggered to switch to filter view only by changing
window focus.

This fixes the window re-focus bug. Unfortunately I couldn't find a much simpler
way to fix this. PTAL.
