Next-gen project statuses appearing on "Time in status" gadget or "Sub-task blocking condition" causes confusion

Summary

If a user has next-gen projects, they will see statuses from those in the following pages:

• Gadgets that use the Statuses in the configuration - "Time in Status" and "Filter Counts", for example
• "Sub-Task Blocking Condition"

Steps to Reproduce

For Sub-Task Blocking Condition:

1. Create a next-gen project
2. Edit a transition of a Workflow for a classic project
3. Click on Conditions
4. Click on Add condition
5. Click on Sub-Task Blocking Condition
6. Observe multiple of the same status (e.g., DONE)

For Gadgets

1. Go to System dashboard
2. Click on Add gadget
3. Add Average Time in Status, for example
4. Observe repeated statuses in Statuses section

Expected Results

Only show one instance of the status.

Actual Results

Shows 1 + (the number of next-gen projects there are). For example, if an instance has 5 next-gen projects, it shows DONE 6 times.

Workaround

1. Change the name of the status on the Statuses page
2. Perform the desired change
3. Change the name of the status back to it's original value on the Statues page
