Can't set ConnectionString on closed connection

[fuxuejun]

When MySqlCnnnection Close, don't change m_hasBeenOpened to false.
So,I can't set connection.ConnectionString wheen I call connection.Close().

The following code fails, but it should work:

using (var connection = new MySqlConnection())
{
	connection.ConnectionString = connectionString1;
	connection.Open();
	connection.Close();

	connection.ConnectionString = connectionString2; // fails here
	connection.Open();
	connection.Close();
}

Fixed in 0.44.0.
