The shardsvrDropIndexes, when running with the feature flag DropIndexesDDLCoordinator enabled, does not always returns directly the completion status of the coordinator because we want to preserve the 'raw' field, which contains the response of all the participant shards.

The shardsvrDropIndexes logic to return a response must be the following one:

• The shardsvrDropIndexes must return the completionStatus if it differs from the result's error code; otherwise result must be returned to preserve the 'raw' field.

The goal of this task is to update the code to fullfill the mentioned condition.
