Minor bugs in HandlePolicyViolationError example

[Tomas Rimkus]

At least the PHP example -> https://github.com/googleads/googleads-php-lib/blob/master/examples/AdWords/v201409/ErrorHandling/HandlePolicyViolationError.php has a couple of minor bugs:

* In case the first mutate request succeeds, the second one will be executed anyway because it's outside catch block

* There is no need to check the size of $operationIndicesToRemove before running foreach loop on line 108

Hi,

Thanks for pointing this out. Could you open an issue on the PHP library's github page?

Thanks,
