[Findit] Fix 'Trigger same task twice' error.

There are duplicated test names in all_tests which leads to this error.

Fix this issue by only include one test in requested_tests_to_run with the same name as each step_name in requested_tests.

Reopen this bug, because the same error still occurred after the recipe change:

Issue 610836 has been merged into this issue.

This seems to happen again these two days.

Chan, if you want me to dig into this bug, please feel free to assign it to me. I will take a look once I get time (possibly in a week).

Thank you for your help. I'll re-assign this bug to you. And please keep me updated about what happened.

Close as this didn't happen for the past 4 months.
