KRACOEUS-7270: data migration for parameters to proposal person roles

Yeah. So here is the code that I removed and in this roleId would be 'PI' only. There was never a real role id of nih.pi.
```
-    protected boolean isRoleReadOnly(String roleId) {
-        if (roleId == null) {
-            return false;
-        }
-        String parmValue = getParameterService().getParameterValueAsString(KC_GENERIC_PARAMETER_NAMESPACE, KC_ALL_PARAMETER_DETAIL_TYPE_CODE, READ_ONLY_ROLES_PARAM_NAME);
-        return parmValue.toLowerCase().contains(roleId.toLowerCase());
-    }
```
