Filter out anything that doesn't end in a flex trip

Now I remember why I excluded bus trips from the flex query, as it might lead to trips like the above.

@hbruch We don't want those in the flex view, isn't it?

We definitely don't won't trips without flex leg. Is 22:34-23:04 a stay-seated in RT794 suggestion with to door delivery? Then we should not remove it.

That's something I'm investigating. @flaktack mentioned in the dev meeting that there is a problem with the transfer.
