Right. This is a 'everyone is surprised and spends two seconds going' @.@ situation.
It is possible for some of the members on one side to be surprised and not all, or for some members on both sides to be surprised, etc, but if everyone is unaware of each other until initiative is rolled, then initiative is rolled normally.

Remember, the test is not whether you are expecting the another party. The test is whether you are aware of the other combatant.
In your example, at the moment the door was opened the goblins and the party were aware of one another. Presumably, they were also aware that they were each other combatants.
So in your example everyone became aware of combatants at the same moment. Accordingly, no one was surprised. So no surprise round. Therefore, the wizard's divination abilty never comes into play.
