Adding reroute node before "GetClassDefaults" disconnects output

Outputs from "GetClassDefaults" node will break if a reroute node is used between input and node.

Does not occur in 4.18

1. Create a new blueprint project & open the default level blueprint
2. Grab a reference to the Bp_Sky_Sphere
3. Create a GetClassDefaults node and plug in the Sky_Sphere
4. Use any of the output variables (ex: Printed the SunHeight float)
5. Add a reroute node between the "GetClass" and "GetClassDefaults" nodes

All output links from the "GetClassDefaults" node will immediately break. If manually reconnected, they will break again on recompile.
