Fix tx re-ordering bug in test:

Browse Source 
`env.fund` requires two transactions: `pay` and `set account`. If there is a
`trust` transaction in the same set of txs, the txs may be reordered so
`pay` -> `trust` -> `set account` so the wrong `no ripple` flag would be used
on the trust line.

Adding a `close` between `env.fund` and `env.trust` resolves this problem.
