#4289: A multipolygon is inverted in ST_AsMVTGeom in some cases

Comment (by Algunenano):

 > Using the 4096 resolution with PostGIS instead of 256 seems to be a
 working solution for my case.

 Yes, the bug appears to be related to small parts left behind around the
 clip borders, so making the polygon 16x bigger solves it in this case.
 Nevertheless I'll try to have it fixed for the next patch release.
