PRs made to the DynamoRevit repo will need to be cherry-picked into all the DynamoRevit Release branches that Dynamo supports. Contributors will be responsible for cherry-picking their reviewed commits to the other branches after a LGTM label is added to the PR.

Purpose

Per https://jira.autodesk.com/browse/DYN-3855, guarding for null exception. Notice that I was not able to reproduce the crash but by reading the code it seems only owningWorkspace being null could cause the crash. Let me know if you have other thoughts. Since state machine is strictly private under WorkspaceViewModel, seems no way to unit test it.
