Bolt deserialization error and nodes missing after pressing Undo when Update Coroutine with Wait node is present in graph

Package: Bolt

-

How to reproduce:
1. Open attached project "BoltUndoLostData_stripped6.zip"
2. Enter Play mode
3. In Hierarchy select "directional Light"
4. In Inspector press "Edit Graph"
5. In "Flow Graph" window, create and enter into "Super Unit" node
6. Delete the Output node
7. Press Ctrl+Z (or do undo in any other way)
8. Observe the Console window and the main Flow Graph

Expected result: no errors are thrown, the Output node is present
Actual result: "\[Deserialization]" error is thrown, Output node is not coming back, the main graph has nodes missing

Reproducible with: 2019.4.0f1, 2020.1.0b12, 2020.2.0a14 (Bolt 1.4.12)
Could not test with: 2018.4 (unrelated errors), 2019.4.0f1, 2020.2.0a14 (Bolt 2, was unable to find 'Super Unit' node)

    Resolution Note (fix version 1.5.1-pre.3):

    Graph rebuild has been delayed to the frame after deserialization to avoir the StopCoroutine issue while in deserialization.
