Consequence of removing /var/lib/ofono or of the error message?

If the former, then that is a heavy-handed way of clearing all settings 
oFono stores on disk, including the sim EF cache.  In your previous log 
the contents of EFspn were being read from cache.  So I just told you to 
wipe the cache so the contents show up in the AT log.  Otherwise I'd 
have to give you complicated directions on how to read the contents ;) 
If you want to know more about the EF cache itself, just ask me on IRC 
some time.

For the error message, it was actually a bug I fixed in commit 
54de04a828d945e8f081c7cd99161881736666b8.  The error message was being 
printed, yet things still worked correctly (by luck.)  You should not be 
seeing that message pop up again.
