Show e.g. 'anchors' again in the Outline

This reverts commit 62b83fcfd, which was about filtering 'ghost'
elements out like "Rectangle { id }", where id was parsed as a
UiObjectDefinition. Unfortunately, "anchors" also is represented as
an ObjectDefinition ... Anyhow, the original problem does not
occur any more, so we can just revert this.
