[GustavoDinizMonteiro]

On start application, that try recreate indeces on database but raise Exception.

Unhandled rejection MongoError: Index with name: email_1 already exists with different options at Function.MongoError.create (error.js:31) at (/app/node_modules/mongodb-core/lib/connection/pool.js:497) at authenticateStragglers (/app/node_modules/mongodb-core/lib/connection/pool.js:443) at Connection.messageHandler (/app/node_modules/mongodb-core/lib/connection/pool.js:477) at Socket.<anonymous> (/app/node_modules/mongodb-core/lib/connection/connection.js:331) at emitOne (events.js:116) at Socket.emit (events.js:211) at addChunk (_stream_readable.js:263) at readableAddChunk (_stream_readable.js:250) at Socket.Readable.push (_stream_readable.js:208) at TCP.onread (net.js:594)

This error probably caused by a bug on update indexes on mlab mongodb instance.
