Update SQL in InitialCreateScript.cs

I ran into a problem when installing to a SQL server instance.  I found that table names were created as [MYSERVICEACCOUNTNAME].[TableName] rather than [dbo].[TableName].  I'm proposing that adding [dbo]. before each table name in this script will create the correct table names.
