[GraphHopper] There must be bug on the subnetwork removal

[John Zhao]

Interesting,
when I increase minOnewayNetworkSize from 20 to 50, the following two
disappeared.
subnetwork start from: 37.32611992939085,-121.9961998312816 size: 24
subnetwork start from: 37.78373608999855,-122.25065187925067 size: 34

*Best Regards,*
