Expose answer_received as an event to Hub

[spalladino]

Whenever a new answer is received in Pollit, push a notification to hub with:

• Poll (title and ID)
• Question (title and ID)
• Respondent (phone)
• Occurrence (datetime, for recurrent polls)
• Answered at (datetime)
• Answer (text)

The properties are displayed when creating a new Hub Task. New answers are not received as events by the Hub. I tried to insert the new answers in a google spreadsheet but answer properties were not stored in the spreadsheet.

Pollit Version: 560fb1a7376673585fc029f81d642a7f2f6cd2fe Hub Version: 1a700c0

To reproduce it: Given a Poll 'Foo' with a enabled channel Go to the Hub Add a new Task Choose 'New Answer' from 'Poll Foo' as Event Choose a GoogleSpreadsheet as Action Add a Field 'Answer' Drag the pill 'Response' into the new Field 'Answer' Save the Task Start the Poll 'Foo' (Pollit) Answer the Poll questions Open the GoogleSpreadsheet

Obtained: A new column was added ('Answer'). This column is empty. Expected: The column 'Answer' should include the new answer

The issue was an error in the hub.yml config file in staging
