The OTP configuration is failing when LDAP is configured to don't import users (read-only) in RH-SSO 7.4

Issue

OTP can't be configured when LDAP Import Users is false and read-only. RH-SSO 7.4.7 doesn't show any message and goes directly to the application. Testing on 7.4.8 we get the following error:

13:07:01,223 WARN [org.keycloak.services] (default task-6) KC-SERVICES0013: Failed authentication: org.keycloak.models.ModelException: Not possible to write 'required action CONFIGURE_TOTP' when updating user 'bwilson'
