Timeline name changes do not propagate to related nodes

Timeline name changes do not propagate to related nodes. Refresh All does not rename nodes that reference the timeline, and Getters and Setters are no longer valid nodes.

Reproduced in 4.7.2 binary and Main (//depot/UE4/Promotable-CL-2479729)

1. Open any project
2. Create a new Actor Blueprint
3. Add a Timeline named Timeline_0 to the Event Graph
4. Add a Play from Start (Timeline_0) node
5. Get Timeline_0
6. Compile/Save
7. Rename Timeline_0
8. Compile

Result:
The Play from Start node gives an error: "Error This blueprint (self) is not a TimelineComponent, therefore ' Target ' must have a connection." The Timeline_0 getter is greyed out and gives the error: "Error The property associated with Timeline 0 could not be found"

Expected:
When the Timeline's name is changed, nodes that reference it also update.
