Summary: Changing mvcc again. This should be double-checked since it's quite a substantial change. The test here tests for the new behaviour - which should be correct.

Summary:
`Where` can now be constructed in a `QUERY`, instead of requiring manual
addition to `Match`. For example:
auto query = QUERY(MATCH(pattern), WHERE(expr), ...);
compared to:
auto match = MATCH(pattern);
match->where_ = WHERE(expr);
auto query = QUERY(match, ...);
Similarly, `AS` can be used instead of `NEXPR` to create
`NamedExpressions` only with a name. This is meant to be used with
`RETURN` which will look at the previous `Expression` and store it
inside `NamedExpression`. For example:
auto ret = RETURN(IDENT("n"), AS("n"),
PROPERTY_LOOKUP("n", prop), AS("prop_val"));
compared to:
auto ret = RETURN(NEXPR("n", IDENT("n")),
NEXPR("prop_val", PROPERTY_LOOKUP("n", prop)));
