Could not remove validation file: No such file or directory - error when forced to renew

[tometzky]

When simp_le 0.18.1 is forced to renew a recently created certificate with "--valid_min=7776000" (for testing), it renews the cert successfully, but before finishing, it fails with an error (names changed for privacy):

simp_le \
	--verbose \
	--vhost example.com:/var/www/example.com \
	--email tometzky@example.com \
	--valid_min 7776000 \
	-f account_key.json \
	-f account_reg.json \
	-f key.pem \
	-f full.pem

It looks like the program is trying to remove validation file even if it did not need to create one. Based on /var/www/example.com/.well-known/acme-challenge/ timestamp, it was not created while renewing. I suppose validation for the account was still valid from the previous renewal.
