Fix ReadTest for L2SQL.
Fix ReadTest for L2SQL.

L2SQL doesn't support some of the functionality tested for here, so we disable
the tests so that we can get a "green"er NUnit test run.

The ReadTest_D13_ExecuteQueryObjectProperty() test was itself actually buggy;
it was executing the query: 

	SELECT [ProductID] as PenID 
	FROM [Products] 
	WHERE [ProductName] = 'Chai'

but constructing it over an object that didn't have a PenID member:

	class Chai
	{
		internal int ChaiId;
	}

Correcting the query to use a field that did exist in the class allowed things
to work as expected under L2SQL, SQLite, and SQL Server:

	SELECT [ProductID] as ChaiId
	FROM [Products] 
	WHERE [ProductName] = 'Chai'
