Implement proper async call of sagas about articulate

@malave when I select a domain in the intent list page the list doesn't always load is that related?

Also the client error console fills up with

Unhandled Promise Rejection: Invariant Violation: parentComponent must be a valid React Component

every time I navigate to a list page. Is that related?

I created #59 just in case

Errors reported by @dcalvom:

• When you create an agent the redirect is to http://localhost:3500/wizard/entity-intent instead of http://localhost:3500/wizard/domain
• The combo of domains in the intent list page was loaded, but was once you pick any domain the intents list isn't loaded. If you click again in the intents - link in the menu the domain list goes empty
• AgentName is not being filled in the webhook request
• The list of domains wasn't loaded, if you click on the domains link in the menu twice, the list is loaded.
• Agent entities wasn't loaded, if you click twice in the entities link in the menu, the list is loaded.
• The intent post doesn't have the intent name inlcuded. In the past once the intent was created the reference to the id was pssed
• Delete agent doesn't works
• Delete domain, intent and entity doesn't works (I don't know if this is already implemented)
