Make tests works on systems with non english datetime format

[MrJingle]

If you set the system Date and Time format to Italian( or any other culture with a different date format than MM/dd/yyyy) the type initializer for NorthWindData will throw an exception on:

[...]
HireDate = ParseDate("8/14/1992 12:00:00 AM"), // the default it-IT date time format is dd/MM/yyyy
[..]

Exception details:

Test Name:  Any_simple
Test FullName:  Microsoft.Data.Entity.InMemory.FunctionalTests.NorthwindQueryTest.Any_simple
Test Source:    d:\MrJingle\Dev\Git\Forks\EntityFramework7\test\Shared\NorthwindQueryTestBase.cs : line 54
Test Outcome:   Failed
Test Duration:  0:00:00,001

Result Message: 
System.AggregateException : One or more errors occurred.
---- System.TypeInitializationException : The type initializer for 'Northwind.NorthwindData' threw an exception.
-------- System.FormatException : String was not recognized as a valid DateTime.
---- The following constructor arguments did not have matching fixture data: NorthwindQueryFixture fixture

The fix is simply to change any occurrence of

   DateTime.Parse("date string")

with

   DateTime.Parse("date string", new CultureInfo("en-US"))
