Unit tests for "all-your-base" too strict in exception handling

[HugoRoss]

All unit tests of exercise "all-your-base" that expect an ArgumentException should expect it with Assert.ThrowsAny(Of ArgumentException) instead of Assert.Throws(Of ArgumentException) which then would allow more accurate sub-exceptions like ArgumentOutOfRangeException to be thrown.

[ErikSchierboom]

That is certainly a valid option. Another would be to change the expected exception to the "proper" exception (e.g. ArgumentOutOfRangeException). I'd be in favor of the latter option, as it better teaches the student which exception is appropriate in which situation. Would you be willing to submit a PR?
