Undefined identifier during component refresh

[StephenEsser]

Issue Description

A refresh call is being made to an undefined component. This is likely due to queued undo / redo actions. We should prevent a user from stacking multiple refresh actions into a queue.

Error

undefined is not an object (evaluating 'fetch(id).url')

Expected Behavior

Multiple refresh actions should not be queued. A new action should wait until the previous action is completed to prevent a call to refresh on an undefined component.

Current Behavior

The redux store may no longer contain a component and throws an error.

Steps to Reproduce

1. Create a workspace
2. Add multiple components into the workspace
3. Repeatedly use the keyboard shortcuts for undo / redo
4. Observe the refresh eventually throws an error.
