TestCases dont inherit Isolated attribute from TestFixture

Currently it is possible to specify Isolated attribute on method and class level. If attribute is specified on class level (together with TestFixture if using NUnit), then it is applied to individual tests.

NUnit 2.5 supports new attribute: TestCase. This can be used for row testing, to run parameterized tests.

But when a test method does not have Test attribute - only TestCase - it does not get Isolated behavior.

This does not work:

[TestFixture, Isolated]
public class MyClass
{
[TestCase(...)]
[TestCase(...)]
public void TestMethod(...)
{
}
}

But this works:

[TestFixture, Isolated]
public class MyClass
{
[Test]
[TestCase(...)]
[TestCase(...)]
public void TestMethod(...)
{
}
}

Since NUnit does not require Test attirbute to be used with test cases, I believe Isolator should do the same and make using TestCase attribute alone sufficient.
