Most of them are NUnit tests, which don't care what source language the assembly under test is written in.

A few of the oldest FogBugz tests are in `unitTest.asp` and were written in Wasabi. They got transpiled over to C# like everything else. Some are confirming Wasabi language features (e.g. `testLambda`, `testDictionary`, `testErrorHandling`), so I could remove them.

All of Wasabi's unit tests were deleted with Wasabi.
