      Server returns a confusing message when recreating an index with the same options that already exists on the server:

      Index with name: key_1_namespace_1_workflowLocale_1 already exists with different options
      

      To reproduce:

      1. Restore the attached bson file:

      $ mongorestore --drop -h Cluster0-shard-0/cluster0-shard-00-00-07vah.mongodb.net:27017,cluster0-shard-00-01-07vah.mongodb.net:27017,cluster0-shard-00-02-07vah.mongodb.net:27017 --ssl --username angelamorgan --password xxxx --authenticationDatabase admin -d t /Users/angelamorgan/Downloads/00502901/b2c-experience-extra-light/b2c-experience/aposDocs.bson

      2. Run getIndexes() on the collection aposDocs:

      	{
      		"v" : 2,
      		"unique" : true,
      		"key" : {
      			"key" : 1,
      			"namespace" : 1,
      			"workflowLocale" : 1
      		},
      		"name" : "key_1_namespace_1_workflowLocale_1",
      		"partialFilterExpression" : {
      			"key" : {
      				"$exists" : true
      			},
      			"type" : "dgad-i18next"
      		},
      		"background" : false,
      		"ns" : "t.aposDocs"
      	}
      
      3. Recreate the index key_1_namespace_1_workflowLocale_1 on the collection aposDocs:
      ```
      MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.aposDocs.createIndex({ key: 1, namespace: 1, workflowLocale: 1 }, { partialFilterExpression: { type: 'dgad-i18next', key: {$exists: true} }, unique: true, background: false })
      {
      	"operationTime" : Timestamp(1530885953, 1),
      	"ok" : 0,
      	"errmsg" : "Index with name: key_1_namespace_1_workflowLocale_1 already exists with different options",
      	"code" : 85,
      	"codeName" : "IndexOptionsConflict"
      }
