Namespace adminNoticeUADismissHandler to prevent callback error

It looks like you forgot to add the PixelYourSite namespace to the adminNoticeUADismissHandler function. This results in the following error: PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function "adminNoticeUADismissHandler" not found or invalid function
