Prevent old more info control to be created

[bramkragten]

Proposed change

Because the more info control tag would be set in updated, we would first load the previous more info dialog control. Moved it to showDialog, as that is the only moment the entity id will change.

Alternative would be to set _moreInfoType to undefined in closeDialog/showDialog.
