Setting only required default scopes for test realm

[anchita-g]

Description of what I changed

#101
To remove the extra claims regarding roles and emails in the test realm that we setup for sample tokens, explicitly set the defaultClientScopes while creating the realm. Also remove the group protocol mapper for this realm.

For test-smart, the extension that we use to enable SMART-on-FHIR already takes care of setting these claims up to the requirement.

E2E test

TESTED:

After the required changes, tested by issuing a token for both the realms.

For test realm, the token's payload when decoded used to look like this before:
