Empty routing key throws some error

[fizerkhan]

When you have empty routing key, trailing / causes 'Action Not found' error. There are two things need to be solved here.

1. Can you please check for empty routing key(not only for null check) and add it in URL once if it is there. If no routing key, there should not be trailing /.
2. VictorOps returns errors in HTML. It is bit weird. It breaks the library at data = JSON.parse(response);, and It stops my server. However this is a bug from VictorOps. Can you please handle it in the library.

PS: You can check everything using following command

curl -vv --data-binary '{"message_type":"critical", "timestamp":"'$(date +%s)'", "entity_id":"disk space"}' https://alert.victorops.com/integrations/generic/20131114/alert/[YOUR_API_KEY_HERE]/[ROUTING_KEY_HERE]
