Next-gen projects causes errors on Permission Schemes when loading issue panel

Permission Schemes can have some problems with next-gen projects (Agility projects).

While creating an Agility project, it will create by default new scoped-project issue types and roles. This means we will have duplicated issue types and role names when creating Permission Schemes.

Since we were using the role name as unique, sometimes we can use a wrong id to make the role actors requests. We should make sure we get the right role id to get the project actors.

*The REST API isn't ready yet to find a better solution to present the duplicated issue types and roles.
