Fixed crash when KeyboardFocusManager clears the focus

[problem] There is crash if focus indicator is empty but KeyboardFocusManager
          tries to clear the focus.
[cause] It doesn't check whether focus indicator exists before remove it from
        the current focused actor.
[solution] Check whether focus indicator exists before remove it.
