Two tests incorrectly branch on TestData.auth in an attempt to only run when the cluster has authentication set up and enabled:

• https://github.com/mongodb/mongo/blob/5b0aeb5f97b83e100de4fa8eee46beeccdf9791d/jstests/sharding/sharded_data_distribution_auth.js#L12
• https://github.com/mongodb/mongo/blob/5b0aeb5f97b83e100de4fa8eee46beeccdf9791d/jstests/sharding/all_collection_stats_auth.js#L12

These tests return early from the "regular" sharding suites, but are actually excluded by sharding_auth: https://github.com/mongodb/mongo/blob/7ac62bbf3a3bc62acac296c1a758a812038cede2/buildscripts/resmokeconfig/suites/sharding_auth.yml#L13-L16
