fix
tc301 done
Added no.18, allow head of lab to finish when all documents are uploaded.

Because the status changes automatically when the documents are uploaded, the Lab Head should be able to mark the current test as PASS or FAIL.

Specifying this explicitly in the use case makes it clearer and more complete for testing.
Update test plan: when all documents are uploaded, allow the lab head to submit result back.

Also, change some wording.
