Do not validate taxids when using -onlydesc in rfci.pl

[AntonPetrov]

The following command

rfci.pl -onlydesc -m 'Fix characters in AU line' RF04184

resulted in an error:

ERROR trying to fetch taxids from genbank, reached maximum allowed number of failed attempts (10)

The family was successfully checked in after a few attempts, but in general -onlydesc should have prevented the taxid check.

Seems like the problem is in _commitEntry of Commit.pm.

More logs:
