Bug 18732: Noisy t/SMS.t triggered by koha_conf.xml without sms_send_config

Upgraded systems may be lacking sms_send_config which makes t/SMS.t noisy.
This silently bypasses the problem.

Remove sms_send_config from your koha-conf.xml file
prove t/SMS.t
-- it will be noisy, but pass.
apply patch
prove t/SMS.t
-- noise gone.
run koha qa test tools.

Works correctly as indicated by the testing plan.
No "uninitialized" noise after patch is applied.

Slightly amended: turned the iif around.
