Fix exception when no actions configured.

[malithie]

Resolves wso2/product-is#21383

Proposed changes in this pull request

This PR fixes the case where an exception will thrown from ActionExecutionService when no actions are configured in the system.
So when no actions configured or if there's a failure in retrieving actions for the flow it will be considered as a scenario where no actions are applied. Thus, token issuance works as expected the state before.
