runner: Don't try to execute an empty set of subtests

If we resume a test run with igt_resume, or if resume is done
automatically from a test timeout, the runner will execute the last
attempted test with the subtest selection set to original set minus
the subtests already journaled to have started. If this results in an
empty set, we get a harmless but misleading message from the test
saying

"igt_core-WARNING: Unknown subtest: subtest-name,!subtest-name"

If the journal already contains as many subtests as we have requested
(when we know the set), assume we have them all already and move to
the next job list entry instead.
