Remove var_dump() in SafariNotification.php

[davidgorges]

SafariNotification.php contains a var_dump() in Line 180. Should be removed.

Happy to create a pull request if wished.

Oops, just figured out you merged the SafariNotifaction service with iOS into AppleNotification service. I guess this will be fixed as soon as the branch is merged into the master. However, there's also a var_dump() in the current fix 1.2 branch (AppleNotification).
