Removed failure category for the tests which are started Passing.

Based on the mail from EC for Failure category, it has reported around 21 Test Cases which are now passing. I have removed their failure category and re verified them by running locally.

Please refer to the mail from EC with subject line. "DynamoCategoryFailure:master"
