[MetricsAdvisor,test] Fix listing datafeed live tests (Azure#11787)

We have a scenario to rename the datafeed so the listing by the
"js-test" prefix would only return one result thus break listing
tests' assumption.

Fixed by moving listing to after creating three data feeds so we still
have two data feeds with "js-test" prefix.
