Fixes #2549
When a VLE path is bound via MATCH p = ... and the bound vertices are
subsequently DETACH DELETE'd, RETURN p raises an internal stale-TID
error because the VLE path materializer (build_path) lazily fetches
vertex/edge properties via heap_fetch after the underlying tuples have
been deleted.
This commit adds tolerant variants of get_vertex_entry_properties and
get_edge_entry_properties that return an empty properties object ({})
when the stored TID no longer resolves to a visible tuple, allowing
the path to be projected with the vertex present but its properties
empty.
