Duplication of timer names doesn't return an error

Just finished debugging an issue whereby one timer was running but another was not.

The cause was two timers with the same name, defined in convox.yml e.g.

timers:
  topic-download:
    schedule: "21 */4 * * ?"
    command: bundle exec rake collection:topics
    service: workers
  topic-download:
    schedule: "0 */1 * * ?"
    command: bundle exec rake collection:topics["customTag"]
    service: workers

IMO Convox should return an error to allow correction of the syntax, instead one of the jobs was over-ridden.

Thanks for flagging that @rob.sharp, will take a look!
