MongoDump fails to backup configServer of sharded cluster in version `5.0.x`

Problem Statement/Rationale

While trying to take backup of a configServer of a sharded cluster with –oplog, I'm seeing this error:

Failed: error creating intents to dump: error creating intents for database config: detected resharding in progress. Cannot dump with --oplog while resharding

But actually, there is no resharding in progress.

Steps to Reproduce

Run mongodump on a configServer replicaSet with --oplog on a newly created sharded cluster.

mongodump --archive --oplog -u <username> -p <pass> --authenticationDatabase admin --host <configServer hosts>

Expected Results

Expected the backup to be successful.

Actual Results
