Summary

When there are multiple fields with the same name (ie Team), Field Required Validator only shows the one that was added recently. This prevents user to use the correct custom field.

Steps to Reproduce

1. Have Jira Portfolio and Tempo installed. Each of this add-ons has "Team" custom field.
2. Below is the current result of all Team fields from DB:

   id	cfname	description
   10024	Team	Tempo Team Custom Field
   13900	Team
   15400	Team	Tempo Team Custom Field

3. Add Fields required Validator to any workflow transition.
4. Depending which field that has the bigger ID, it will be shown. In this example, Team field from Tempo will be shown in the list of fields in Workflow validator and when the user wanna add Team from Jira Portfolio, it's not possible.
5. Create another custom field called Team

   id	cfname	description
   10024	Team	Tempo Team Custom Field
   13900	Team
   15400	Team	Tempo Team Custom Field
   15831	Team	This is Testing

6. Now, the Team field that is being shown is the newly created custom field (Not Tempo nor Porfolio)

Only the latest added field will be shown.

All fields should be shown.
