Temporarily remove PHP_CodeSniffer from the Travis test matrix.

Before refactoring the data store or CLI command to fix the outstanding CodeSniffer issues (SQL escaping), we should have tests around them. In order to test those methods effectively, we need factories for things like products, orders, discounts, etc. — that feels way out-of-scope for a seemingly-innocent "coding standards cleanup" branch (though it absolutely needs to be addressed before a public release, as SQL injection is nothing to scoff at).
