APN connection timeout

We are getting the following issue in production. Is it possible to update to the newer version of node-apn? It seems like it was fixed in version 1.7.2 (https://github.com/argon/node-apn/issues/217).

```
Connect timed out stack:Error: Connect timed out
at Connection. (/bundle/bundle/programs/server/npm/node_modules/meteor/raix_push/node_modules/apn/lib/connection.js:193:36)
at Timer.listOnTimeout [as ontimeout] (timers.js:121:15)
```

Start with the node-apn 1.7.2 fix referenced in the issue and the timeout location shown in raix_push/node_modules/apn/lib/connection.js. Determine how this dependency is included, then verify that the update prevents the APN connection timeout; the issue provides no named test, so validation must focus on the reported production failure.
