File containing only a namespace declaration raises undefined index notice

[aik099]

Here is the line with error: https://github.com/squizlabs/PHP_CodeSniffer/blob/master/CodeSniffer/Standards/PSR2/Sniffs/Namespaces/NamespaceDeclarationSniff.php#L68

As seen from code it looks for next whitespace after namespace declaration, but since it's last code in file and this is never asserted then error happens.

I think this fix should go in master branch and then merged to phpcs-fixer branch.

I've fixed this up in both branches now. Thanks for reporting it.
