Rusty Russell 1dc281c111 pytest: test for pay adjacent routehint crash.
When route returns a result which is too expensive, we try to figure out which
hop is most expensive to exclude it for next time.

If it's a single-hop route, we don't count it, since the first hop is free.
That's not usually a problem, since single-hop routes can't exceed our limits
(they're always "free"!).

But if we are using a routehint, the total cost could exceed our limits,
even if the start of the routehint is a single hop away.

This reproduces that test case.
