bug(actionRunner): when action run fails, message does not contain error

[prescottprue]

Describe the bug
When running an action - if the action fails, the message should be clearly visible to the user. It would also be good if this could be accessed in the events view.

To Reproduce
Steps to reproduce the behavior:

1. Go to the action runner
2. Run an action that is bound to fail (i.e. trying to copy an rtdb path)
3. Wait for error to appear
4. Message does not clearly indicate that the failure was because of data not being there (even though actionRunner cloud function does write that message back to the db)

Possible Solution

• Display the message which already exists within the snack that is displayed
• Do the same for browser notification
