Subject: Use the try catch to deal with the StaleDataException.

When test the monkey, the mCursor is not null and the mCursor is Closed.
So that the mCursor cannot call the method of moveToPosition. Otherwise
it will lead to StaleDataException.

In order to prevent the android.database.StaleDataException and IllegalStateException,
use the try catch to deal with the StaleDataException and IllegalStateException.

Test:Perform the monkey test, and See if this android.database.StaleDataException will happen again when call the method of android.media.RingtoneManager#getRingtoneUri.

Bug: 169292273
