FIX: createSchemaIfNeeded for SQLServer

[rPraml]

This fixes createSchemaIfNeeded for Microsoft SQLServer

What does NOT work:

PreparedStatement query = connection.prepareStatement("CREATE SCHEMA " + dbSchema);
query.execute();

Statement query = connection.createStatement();
query.execute("CREATE SCHEMA " + dbSchema);

PreparedStatement query = connection.prepareStatement("CREATE SCHEMA " + dbSchema);
query.executeUpdate();

all of them will throw com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'SCHEMA'
