Expose ExpectedResult to the TestContext

[garyhuntddn]

We have a scenario where we have extensive test cases which use the ExpectedResult argument of the TestCase attribute.

Within those test we have a new need to be able to assess the ExpectedResult.

Rather than convert the tests so that the ExpectedResult is passed in as an argument and an assert performed we would like to be able to examine the ExpectedResult in the same we can see the MethodName and the Arguments.

We've been able to hack together a solution using reflection against the _test field and the internal ExpectedResult property of the TestMethod class but it would be nicer if we didn't have to do this.

See #4100 for a simple PR that exposes this property.

Can you explain your scenario a bit more?
Knowing the ExpectedResult in a test either is cheating or doing Nunit's job to compare the actual result with the expected.
