Pyproj logs PROJ_ERROR at debug level

[adybbroe]

This is equivalent to #822
But while the message "PROJ_ERROR: proj_crs_get_sub_crs: Object is not a CompoundCRS" is now gone I see this

from pyproj import Proj
import logging
logging.basicConfig(level=logging.DEBUG)

p = Proj("+proj=stere +a=6370000 +b=6370000 +lat_0=90 +lat_ts=60 +lon_0=10 +units=m +no_defs")

p.crs.source_crs
# DEBUG:pyproj:PROJ_ERROR: proj_crs_get_coordoperation: Object is not a DerivedCRS or BoundCRS

Problem description

Pyproj ouputs the following error message on debug log level:

DEBUG:pyproj:PROJ_ERROR: proj_crs_get_coordoperation: Object is not a DerivedCRS or BoundCRS

I have started seeing this with Pyproj 3.1.0, whereas the one reported in #822 is now gone. I tested with pyproj 2.6.1 and PROJ 7.1.1 and it is not there.

Expected Output

No log message or at least not a DEBUG message with a PROJ_ERROR.
