Hot reload can prevent code components from being accessible in blueprints

When a class is edited / hot reload preformed, code based components are sometimes removed from the MyBlueprint > Variables section and cannot be dragged from the Components tab into the graph with an error saying "Cannot find corresponding variable (make sure component has been assigned to one)"

I found this was most likely to occur when adding dynamic binding for component overlap / actor overlap events

Workaround:
Restarting the project after the hot reload will reset the components / variables and allow them to be added to the graph again.

Regression:
Yes - this behavior does not occur after hot reload in 4.17.2 (CL 3658906)

Repro Rate: 8/10

1. Download attached project
2. Create a blueprint based on MyActor
3. With both editor and VS open do the following
   • Attempt to select / drag component from Components tab to Graph after each compile
4. Uncomment lines 26&27 in .h & line 12 in .cpp (add MyMesh)
5. Compile through VS
6. Re-comment line 12 in .cpp and uncomment lines 29&30 in .h & line 11 in .cpp (replace MyMesh with NewMesh)
7. Compile through VS
8. Uncomment line 12 (both MyMseh and NewMesh added)
9. Compile through VS
10. Uncomment lines 32&33 in .h & lines 13, 15-17 in .cpp (add TestScene and setup hierarchy)
11. Compile through VS
12. Uncomment lines 35&36 in .h & lin 14 in .cpp (add Skellington)
13. Compile through VS

Result:
When a component is selected in the Components tab, its Details are not displayed. When this occurs, the component cannot be added to the Graph. The Component's Category also disappears from the My Blueprint > Variables section

Expected:
Preforming a hot reload allows previously existing and newly added code to function together.
