fix(files): Ensure renaming state is correctly reset

Problem: Is a node is renamed and the new name is out of the current
visible list of nodes the component will be recycled, this means
the props will change, so when the `onRename` functions is about to reset
the state the `this.source` will point to a different node.

To fix this, but also to separate business logic from visual representation,
the logic is moved into the renaming store and the component is only
responsible for rendering.
