Summary

When updating user picker value during a workflow transition screen, if the transition is blocked due to other system/workflow validator condition, after updating the field needed, the user picker value will not be updated properly

Steps to Reproduce

1. On a freshly installed instance, create a transition screen which has assignee field and summary field
2. Summary field by default has a validator hard coded to it, where this field will need to have a value
3. Append the transition screen to any workflow transition
4. Publish the workflow
5. Trigger the transition screen by performing the needed transition
6. Change the assignee field
7. Remove the Summary value to become empty
8. When saving, the update will fail due to the summary field is empty
9. Insert value to summary field, and resave.

Expected Results

1. Issue will be able to save with updated value for both assignee field and summary

Actual Result
