Comment (by Yury Ryabov):
Digging further into this issue I found out that
`GEOSGeometry.transform()` method actually uses GDAL/OGR under the hood
and not GEOS. On one machine I have both GDAL 2.4 and GDAL 3.0.1
installed and on the other I experimented and with available GDAL versions
having only one version installed at a time. From what I observe it seems
that incorrect transformation result I discovered the first time is
returned when GDAL 3.0.1 is in use. If GDAL 2.4 is in use I get OGR error.
Checked versions of geospatial libraries supported by Django and it
turns out that neither GDAL 3.x or 2.4 are supported. I wish Django
raised exceptions or at least a warning about unsupported versions of
geospatial libraries.
