Add an extra condition to check whether it is the default notification uri

There is a valid case that the default notification uri with `vibration_uri` as the parameter like:
```
content://settings/system/notification_sound?vibration_uri=file%3A%2Fproduct%252Fmedia%252Fvibration%2Fnotification%2FRumble.xml
```
This CL is to enable this case.
