Fix the accessibility shortcut funtionaility.

1) Set default value when the
   Settings.Secure.ACCESSIBILITY_SHORTCUT_TARGET_SERVICE is empty.
2) Fix the filter condition to check if the value is empty or not.

Root cause of the issue: the value of ACCESSIBILITY_SHORTCUT_TARGET_SERVICE is
"", an empty string, which make a11y shortcut no responisble.
