Error while test running a flow in local environment

[apandura-tibco]

Environment

How are you running Flogo Web?

• Docker (Specify the docker image that you're using and the command you used to start the container)
• Other (Provide details of your environment) : Local development environment

Describe the bug

When I start the webUI locally in my system flow test runner is dependent on flow-store which is not documented or automated properly. So whenever I try to test run the flow I get an error notification.

To Reproduce

Steps to reproduce the behavior:

1. Start flogo-web server and client locally in your system
2. Go to the details page of a flow
3. Click on 'Run Flow' button in the header
4. See error

Expected behavior

A better exception handling is needed when a dependency is not working for test running a flow. We can automate the flow-store service execution while starting the flow test runner.
