Description
Create an Azure MySQL 5.7 instance and attempt to connect to it.
A NullReferenceException is thrown:
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
at MySql.Data.MySqlClient.MySqlConnection.CloseDatabase()

After fixing this bug in CloseDatabase, we get the underlying exception:
Unhandled Exception: System.FormatException: Expected to read 0x00 but got 0xFE

When connecting, we are expecting to get an OK packet, but the server is sending a change authentication packet instead.
