Fix #257 - Commented trip request test.
I actually think that would be more interesting to just check for the feasibility of an already known as possible trip, instead of checking all the steps of one trip for one server which may be inconsistent when changing OTP version.
More than that, this test is totally relying on A Coruña server which is unfortunately most of time offline these days..
