Activity does not produce a starting/started event before faulting

[JBBianchi]

What happened:
On the WebSocket stream, an activity of type action doesn't seem to start, it's faulted and executed directly:

(Fault cause: An error occured while evaluting the specified expression: 'jq.exe' is not recognized as an internal or external command,\r\noperable program or batch file.)

What you expected to happen:
The activity to be started before being faulted/executed

How to reproduce it:
Deploy & run the following workflow:

@JBBianchi I'll investigate ASAP, but this might be due to an error during the activity's initialization, which therefore won't start

[cdavernas]

@JBBianchi I was right, the bug appeared during initialisation.
This has been resolved by upcoming 1.0.0.
