Handle nodes that may appear in GraphPattern expression trees expression_tree_mutator_impl() did not handle T_GraphPattern, T_GraphElementPattern, and T_GraphPropertyRef. The corresponding expression_tree_walker_impl() already handles all three node types. This causes an "unrecognized node type" error whenever a GRAPH_TABLE appeared in an expression tree.
While at it, also update raw_expression_tree_walker() and expression_tree_walker() to handle missing nodes that may appear in GraphPattern expression trees. When raw_expression_tree_walker() is called, GraphElementPattern::labelexpr contains ColumnRefs instead of GraphLabelRefs. Hence those are not handled in raw_expression_tree_walker().
