[msbuild] Update Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblie…

…s_* tests.

We're including a new assembly, which means the
Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_* must be updated
accordingly.

Also modify these tests so that test assert that fails lists the actual
assembly that's missing, i.e. instead of this:

    1) Test Failure : Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_Executable
         xamarin#1
      Expected: 6
      But was:  7

we now print:

    1) Test Failure : Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_Executable
         References
      Expected: equivalent to < "mscorlib.dll", "MyLibrary.dll", "System.Core.dll", "System.dll", "System.Xml.dll", "Xamarin.iOS.dll" >
      But was:  < "mscorlib.dll", "MyLibrary.dll", "System.Core.dll", "System.dll", "System.Drawing.Common.dll", "System.Xml.dll", "Xamarin.iOS.dll" >
