Executing via dynamic syntax will not throw SQL exceptions if there are no results

[abe545]

This is easy to demonstrate:

Throws as expected:

Task<IEnumerable<int>> t = db.ExecuteAsync().usp_DoUknownStoredProcedure();

Does not throw:

Task t = db.ExecuteAsync().usp_DoUknownStoredProcedure();

The same behavior is exhibited with await: Throws as expected:

IEnumerable<int> r = await db.ExecuteAsync().usp_DoUknownStoredProcedure();

Does not throw:

await db.ExecuteAsync().usp_DoUknownStoredProcedure();
