[GraphHopper] There must be bug on the subnetwork removal

[John Zhao]

Hi,

I tried car flag encoder with following parameter on San Francisco bay area
data from mapzen.
https://s3.amazonaws.com/metro-extracts.mapzen.com/san-francisco-bay_california.osm.pbf

minNetworkSize=200
minOnewayNetworkSize=20

I printed all the remaining subnetworks.
edges: 591932, nodes 437420, there were 3496 subnetworks. removed them =>
13121 less nodes. Remaining subnetworks:5
The remaining subnetworks are:
subnetwork start from: 37.32611992939085,-121.9961998312816 size: 24
subnetwork start from: 37.56018439442332,-122.30257814308803 size: 436637
subnetwork start from: 37.78373608999855,-122.25065187925067 size: 34
subnetwork start from: 38.180185962770565,-121.70631393878864 size: 301
subnetwork start from: 37.85717050411933,-122.07633641532816 size: 424

I don't understand why there is still subnetwork less than 200 nodes.

I have a look at 37.32611992939085,-121.9961998312816.
It seesm related with barrier=gate at intersection.
