red message box after success exception handling

• import resource, for example samples\resources\csvfile\localhost-csvfile-resource-advanced-sync.xml and set path to midpoint-flatfile.csv - this file contains user01
• create user with name user01, what is existing in target resource.
• add projection to this resource and save it
• operation is success (all activity status is green), because midPoint correctly detect and pair new user with existing account in resource, but red message is showd: "Could not add account object:null(null), because the account with the same identifier already exists on the resource."

It will be better to show warning & partial messages in yelow color, not with red.
You need an advanced user to understand, this message is only warning and not error.
