Update for MongoDB 4

[Mahan-F]

Hi, is it possible to get this package updated so that it can be used with the latest version of MongoDB?

Currently it will break because client.isConnected() is no longer a thing in version 4. (Details here)

The changelog mentions

Remove MongoClient.isConnected - calling connect is a no-op if already connected

I've been releasing v1.0.0 of this package. Glad to see your feedback on this package. Thanks.

Thanks a lot for this, I just had a look at the changes you made and I noticed two things that seem to be not inline with Mongodb 4 changes.

From what I understand, client.isConnected has been completely removed and you just call client.connect() at all times, if there is already a connection, it will do nothing.

 
 ​    ​if​ ​(​!​client​.​isConnected​ ​||​ ​!​client​.​isConnected​(​)​)​ ​{ 
 ​      ​await​ ​client​.​connect​(​)​; 
 ​    ​}

Also on line 118, you are setting user property but this has been changed to username in the latest version.

Don't worry, I just want to give support for the older and newer version of mongodb sdk.

Damn, I missed it up. Ok, I'll publish a new version to fix this problem.
