…he#1426) Fixed issue 1393 - Unexpected error when matching nodes that are connected to nodes resulted from a previous MATCH clause. Basically, variables from the previous clauses where not seen when using the EXISTS clause for path pattern matches. This only affected EXISTS and only for the EXISTS (anonymous_path) grammar component. The original issue was only with vertices, but this also affected edges. Both cases are now fixed. Fixed 1 regression test that was incorrect. Added regression tests.
