A view definition with GRAPH_TABLE depends upon the property graph it references as well as the properties and labels referenced in it. We recorded the dependency on the property graph, but did not record dependency on labels and properties. This allowed properties or labels referenced by a view to be dropped, resulting in a cache lookup error when such a view was accessed. Fix this bug by handling GraphPropertyRef and GraphLabelRef in find_expr_references_walker(). The dependency on the data type of property does not need to be recorded separately as it is recorded indirectly via a dependency on the property graph property itself. Note that a property or a label associated with individual elements can still be dropped as long as there are other elements that are associated with that property or label, since they do not lead to dropping the property or the label from the property graph altogether.
