Connection cursor before and last return wrong result

[choeisai]

I use graphql-compose-connection for my project to make pagination with cursor base.
It worked when I use 'after' and 'first'. But if I used 'before' and 'last', it return wrong expected result.

Case 1
after: "cursor-5", first: 3
result: [r-6, r-7, r-8]

r-0
r-1
r-2
r-3
r-4
r-5 <- cursor
r-6 <- expected result
r-7 <- expected result
r-8 <- expected result
r-9
r-10

Case 2
before: "cursor-5", last: 3
result: []

r-0
r-1
r-2 <- expected result
r-3 <- expected result
r-4 <- expected result
r-5 <- cursor
r-6
r-7
r-8
r-9
r-10

In my opinion, case 2 should return [r-2, r-3, r-4] but it return [].

Yep, you are right.
According to https://facebook.github.io/relay/graphql/connections.htm#sec-Backward-pagination-arguments it should work exactly as you describe.

Will be happy if you can fix it and make PR. I'm really busy with graphql-compose-elasticsearch right now.
