Error on touch with mcrouter

[tomasAlabes]

I'm having the exact same error as #107:

io.sixhours.memcached.cache.MemcachedOperationException: Failed to touch key

In my case the mcrouter config is:

 "pools": {
    "Process": {
      "servers": [...]
    }
  },
 "route": {
    "type": "PrefixSelectorRoute",
    "policies": {
      "my_prefix": {
        "type": "OperationSelectorRoute",
        "operation_policies": {
          "add": "AllSyncRoute|Pool|Process",
          "delete": "AllSyncRoute|Pool|Process",
          "get": {
            "type": "MissFailoverRoute",
            "return_best_on_error": true,
            "children": [{
              "type": "PoolRoute",
              "pool": "Process"
            }]
          },
          "set": "AllSyncRoute|Pool|Process",
          "incr": "AllSyncRoute|Pool|Process",
          "decr": "AllSyncRoute|Pool|Process"
        }
      }

xmemcached version 2.4.6. mcrouter version 38.0.0.

Closing as I don't think it has to do with the mc client.
