APNS: does not change the server's address when switch from sandbox to production

[monnand]

1. Put cert.pem and key.pem under some directory, say /top/secret/cert.pem and /top/secret/key.pem, respectively.

2. Use the following command to add a sandbox provider:

   curl http://127.0.0.1:9898/addpsp -d service=myservice -d pushservicetype=apns -d cert=/top/secret/cert.pem -d key=/top/secret/key.pem -d sandbox=true

3. Download the production certificate and key. Put them under the exact same path as sandbox certificate/key. i.e. overwrite the sandbox certificate/key

4. Use the following command to add the production provider:

   curl http://127.0.0.1:9898/addpsp -d service=myservice -d pushservicetype=apns -d cert=/top/secret/cert.pem -d key=/top/secret/key.pem

5. Now, push message through that provider, the sandbox certificate/key will be used even if it has updated the database.
