TestCases should be able to show their error line at where the test case name is defined

We should be able to do at least a lazy attempt to look for "My Test <Name>" and go thru the AST parser looking for a hashtable with the same name property. If for whatever reason this fails we'd just fall back to the top test name.

This would be static analysis for a string only, any variables used in this location would not work.
