RF 5.0: AttributeError: 'HandlerExecutionFailed' object has no attribute 'full_message'

[oianson]

In RF5.0 when using 'rfshell' or the 'Debug' keyword, when I am using keywords which are failing/raising exceptions I am getting the following error AttributeError: 'HandlerExecutionFailed' object has no attribute 'full_message'

I do not see this on RF4.0
