dovetail tool: check push_to_db success or fail

JIRA: DOVETAIL-380

If Functest fails to push results to db, there is just an error log in functest.log
Dovetail needs to know the failure.
Dovetail will get the results from db with keys, build_tag and testcase.
If it can get the results data, it means push_to_db success.

Fix the duration time wrong.
