* AccessibilityHelpers.cs: If (#689)

AccessibilityNodeInfo.FindAccessibilityNodeInfosByViewId(..) returns
  null when the source package is a supported browser, return a null
  uri to prevent overwriting the existing notification's pendingIntent
  uri extra with the brower's packageName.

* AccessibilityService.cs: Added null uri checks as it is now possible
  for AccessibilityHelpers.getUri(..) to return a null uri when the
  Accessibility Service is misbehaving.
