Repro

1. Use NetCoreWinFormsWam dev app.
2. Clean MSAL cache.
3. Select Use WAM.
4. Login interactively with an account.
5. MSAL cache should have an access token, account, ID token, but no refresh token.
6. Call GetAccounts.
7. Observe that one account is returned but tenant profiles are empty.

Actual behavior
In GetAccounts this code that adds tenant profiles is skipped because there are no refresh tokens in broker flow. And this code doesn't add them.

Expected behavior
Tenant profiles should be returned.
