UIThreadTestMethod should forward DataRow Attribute

[michael-hawker]

LabsUITestMethod currently doesn't look for other attributes when being generated.

We should at least create a pattern/work to enable DataRow for repeated test scenarios.

Looks like ExpectedException is the old pattern and it can be better to use Assert.ThrowsException for more granular control, see blog here with argument.

So we maybe don't want to forward that one or provide a warning when used at least?
