Scenario: Connecting with the Node driver using SCRAM authentication where the password contains a character that needs to be encoded, e.g. @ -> %40

When using the mongodb:// protocol, you can connect with a single level of URI encoding, e.g.: "mongodb://user:myP%40ssword@host/".

When using the mongodb+srv:// protocol and use a single level of URI encoding, e.g: "mongodb+srv://user:myP%40ssword@host/" you get the error:

Error: Username containing an unescaped at-sign

You can get past this by double-URI-encoding the password, e.g: "mongodb+srv://user:myP%2540ssword@host/"
