Vertx stack fails for appsody run and appsody test on Travis

[Kamran64]

Describe the bug
On travis (haven't been able to replicate locally), the appsody run and appsody test portions for Vertx currently fail. This behaviour was seen in #665 which initially only attempted to bump the stack version.

Logs for appsody run:

This is a download/slowness/resource pull issue. If travis isn’t using any kind of dependency caching, this can happen
