Internal exception when creating property graph on non-existing table

[Dtenwolde]

-CREATE PROPERTY GRAPH snb
VERTEX TABLES (tabledoesnotexist);

Result:
INTERNAL Error: Assertion triggered in file "/Users/dljtw/git/duckpgq/duckdb-pgq/src/include/duckdb/parser/parsed_data/parse_info.hpp" on line 43: dynamic_cast<TARGET *>(this)

The problem is that a Catalog Error is thrown in create_property_graph.cpp which triggers the operator extension. However, I don't want this to happen, we just need to return the catalog error
