Policy editor should support displaying roles with upper and lower case rolecodes

[nkylstad]

Description of the bug

Policies can ship with both upper- and lowercase role codes.
However, at the moment, only lowercase role codes from the policy are displayed with the descriptive text for the role. The same role code in uppercase results in just the rolecode being displayed.

Steps To Reproduce

1. Create a new app
2. Open settings modal for the app and go to "Tilgangsregler"
3. See that roles REGNA and DAGL are displayed with role code
4. Add a new role
5. See that it is displayed with a display text rather than the role code.
   

Additional Information

Probably introduced with #11545, therefore adding it to our current sprint.

Jeg har testet dette å endre på rollene for ulike apper nå, og usikker på om det har noe med denne PRen å gjøre ettersom det er en backend feil, men får hvertfall 500 server error når jeg legger til eller fjerner en hvilken som helst rolle 🤔
Har testet både lokalt og på dev.

Dette er konsollen lokalt:

System.NullReferenceException: Object reference not set to an instance of an object.
         at Altinn.Studio.PolicyAdmin.PolicyConverter.GetSubjectAnyOfs(List`1 subjects) in /Users/andreastanderen/Development/DigDir/altinn-studio/backend/PolicyAdmin/PolicyConverter.cs:line 251

Tested this in dev now, and there is still some errors. When a subject is selected from the combobox, and then removed from the list of selected subjects, the subjectid is present in the options list instead of the subject title. I guess that there there is one more usage where we use the title and id wrong in the code 🤔

@WilliamThorenfeldt, your findings have been addressed in the following pull request: PR #12348. Additionally, I've identified some additional issues that need attention, and I've created a separate issue for that: Issue #12349.

@WilliamThorenfeldt, I have retested your observations in dev. I can confirm that I am able to add and remove roles successfully. Additionally, the removed roles are now displayed in the selection list using their titles instead of their IDs.
