Clause of with not work as expect

[LianxinGao]

reference: https://neo4j.com/docs/cypher-manual/current/clauses/with/

match (n: Person)-[r: KNOW]->(m: Person)
with m
MATCH (m)<-[membership:HAS_MEMBER]-(forum)
return forum

In Lynx, this cypher query will product a Join operation, but use with, the correct way should be product a expand operation which will expand relationship from m.

Currently just impl a rule to handle this #201 , more thought is needed.
