fix: Remove early returns in claims transformation

[Alexr03]

Issue:
Current implementation will flow to an early return statement when all of the following requirements are met:

• RolesClaimTransformationSource.All is set
• The user does not have any roles in the requested resource
• The user does have a realm role

Expected Result:
The realm role will be applied to the principal.

Actual Result:
The realm role is not applied to the principal.

Resolution:

• Remove early returns and allow the method to flow to the end where it will return with the final principal.
• Added tests to check for this case.
