Set classname to first ID segment for Polarion matching

The previous fix cleared classname to empty, but jump.py
(helpers.py:143) requires a non-empty classname — tests
without one are skipped entirely ("doesn't have a classname
and therefore it won't be uploaded to Polarion").

jump.py builds the match key as "classname.name" (line 156).
The registered automation-test-ids have the format:
sig-installer.Suite_openshift_openstack.<category>.<desc>

Split the formatted name at the first dot so that:
- classname = "sig-installer" (first segment)
- name = "Suite_openshift_openstack.<category>.<desc>" (rest)

This produces full_name = "sig-installer.Suite_openshift_openstack..."
which matches the Polarion entries (RHOSO-11212 to RHOSO-11266).
